AO Acquistion Camera

Palomar Automated Airspace Safety Systems

Palomar's multi-tiered airspace safety system consists of an all-sky visible camera (ASCAM), a narrow-field mid-infrared camera (IRCAM), and a narrow-beam radar. At present, these are used in concert with human spotters to assure aircraft safety during laser operations.

Beam Transfer Optics

The beam transfer optics subsystem delivers the 589nm laser beam from the Coude lab to the laser launch telescope located behind the Hale telescope secondary. It consists of actively controlled reflective, refractive, and polarization optics.

Conclusions

I suggest replacing the M2 mirror with an enhanced aluminum version, such as CVI part EAV-PM-4050-C ($730). This will get rid of the red dropout, and has >99% reflectivity for S pol 589 nm. The red data suggests there may be a yellow dropout on the current mirror. We have no data on this yet, but it may be prudent to get a mirror on order. The EAV mirror will also eliminate the need for a backstop on M2, as there should be no appreciable light leak through it.

The similarity of the polynomial fits between the two runs suggests that writing a correction equation as John Angione has requested would work.

Follow-up

AB: The following parts were ordered on 5/25/06:

Newport Corporation

Part: 40D20.ER1 (Broadband Metallic Mirrors, 4" diameter, Pyrex, 1/10 wave surface, enhanced aluminum coating) Price: $440 Count: 1

Part: 40Z40.ER1 (Broadband Metallic Mirrors, 4" diameter, Zerodur, 1/20 wave surface, enhanced aluminum coating) Price: $686 Count: 1

All,

I just returned from a long day at Palomar. Here's what I got done on the BtO: (I will also post this on the TWiki site BtO page...)

1. Checked stability and alignment of BtO Coude breadboard

The new breadboard has been mounted to the spectrograph frame using a single wide steel L-bracket along the lower edge. While alignment is good, I'm somewhat concerned about vibrations. A diagonal brace behind might be necessary to stiffen the mount, but this is not an immediate priority. The breadboard surface is parallel to the polar axis to better than 0.10 deg., and parallel to the vertical plane to ~0.2 degrees (the top leans very slightly East). The surface is 3.50" from the polar axis, making this the beam height on the breadboard. No shimming was necessary.

2. Define polar axis

I mounted an iris on the new breadboard, centered on the polar axis as defined by the 635nm diode laser installed last week. This laser allowed us to transfer the knowledge of the location of the polar axis from the old breadboard to the new one. I expect this iris is within ~3mm of the true polar axis. The other point defining the axis is the center of the Coude output window (well, not exactly the center - actually a point 2/3 of the way up, along the central axis).

3. Simulate CSFL beam

I set up an unpolarized HeNe? laser to reflect off a mirror placed in front of the CSFL shutter, to replicate the geometry of the yellow laser for alignment and testing.

3. Populate BtO Coude breadboard.

I installed all optics, stages, and the 660nm polarized diode laser on the new breadboard. These were aligned to the simulated CSFL beam and polar axis. The simulated CSFL and 660nm beams are now co-aligned, and reflect off the FSM onto the polar axis. I took some photos of the setup, but my camera apparently doesn't feel like showing them off right now.

NOTE: I may have installed the 1/2-wave plate rotary stage backwards from its previous orientation due to mounting constraints. If this is the case, a sign will have to be changed in the software controlling this motor.

Tasks left for next week:

I ordered a few small parts which will simplify some of the optomechanics - these should arrive at Palomar tomorrow (6/2). After installing these, we should be ready to test the Q1 and Q2 signal levels with the 660nm laser. This will be a repeat of the testing Chris and John did 2 weeks ago, with new optics on the Coude breadboard, the enhanced-Al mirror on the trolley, and RG610 filters in front of quad cells - all are in hand. Other than this, I don't think there is really much more to do until we have yellow light to work with. I will discuss with Viswa when we might be able to do this.

Sincerely,

Antonin

From C. Shelton, 06/02/06:

Here's a to do list, at least what I can remember. Is there anything else you can think of?

Finish the "tasks left for next week" from your email (below). Find waveplate zero position, record it in Default file. Check Q1, Q2 signal levels at zenith Add Q2 baffle, or at least check Q2 alignment as we did for Q1. Recheck signal levels at zenith, test and debug if needed all remaining lock modes Insert polynomial correction on m2_x and m2_y Move telescope, check signal levels and polynomial correction vs pointing. Add and test separate loop-dropout and safety thresholds (red, yellow thresholds) Test interactions with safety system (test of pieces -- full test requires yellow beam, LaserLaunchTelescope).

In your original alignment, how did you go about establishing the coude end of the polar axis? You explained how you spun the telescope to get the upper end.

I'll also coordinate with John A.

When is there likely to be a yellow beam? An LaserLaunchTelescope?

Cabling and Data Transfer

by Anna Moore and John Henning

The following summarises the current cabling installed on the 200inch telescope. We describe how signals from both benches are carried to the computer room that is the central hub for communications. From this location signals can be routed to the data room in which the diagnostics pc for this run will be located.

Current cabling existing at 200inch:

o There are (27) 50-ohm coax lines, (12) 62.5u multimode fiberoptic lines, and (120) general-purpose copper conductors at the prime focus cage.

o All the fiberoptics have ST-type connectors and run to the Cass cage, whence they can be routed to the computer room (CR).

o Six of the coax have BNC connectors; they run to Cass and can be continued to the CR. Fourteen coax have specialized Amp "coaxicon" connectors, but breakout cables can convert these to BNC-- these also run to Cass and potentially to CR. and seven coax run directly to CR.

o The plain conductors, while probably not of interest, run either to Cass or CR.

o It appears that LLT currently uses up to eight of the coax for existing functions, and none of the fibers.

o The cabling distance PF<->CR is ~100meters.

o We currently have (14) 50-ohm coax lines between coude and the computer room. No fiberoptic... but it is a short run and we can run some F.O.cables if that is needed.


Suggested cabling method:

Coude to computer room:
Requirements:

o 3 analog cameras

o 1 photodiode analog output &#61664

Use 4 × 50ohm lines

LLT to computer room:
Requirements:

4 analog cameras

1 photodiode analog output 

1) Analog to GigE? IP engine (Pleora) located at prime focus (up to 6 analog inputs, 2 simultaneous)

2) 1000BaseT(GigE? )->1000Base-SX(short wave optical fiber) converter located at prime focus (arrived)

3) 100m of 62.5 multimode fiber to computer room

4) 1000Base-SX->1000BaseT converter located in computer room (arrived)

5) GigE? into PC PCI card (Patrick has supplied a PCI single GigE? card for testing)

Night logs and results

5/24/07 UT
Laser and BTO setup until 10:00pm. Then checked LLT boresighting no adjustments necessary) and performed some LGS performance tests in partly cloudy conditions. Imaged two science targets at the end of the night. Partly cloudy, seeing ~0.50" in V. 5/24/07 night log

5/25/07 UT
LLT collimation in partly cloudy conditions until 1am. Found LGS and NGS imaged through LLT at 3.5" FWHM, reduced to 2.5" after optimizing collimation (in 0.6" seeing). Shuttered for 2 hours by USAF Space Command. Performanced testing for last 2 hours, in cleear skies. Laser power 5.0 W all night. 5/25/07 night log

5/26/07 UT
6 science targets. Variable seeing. Laser power constant around 5W. 5/26/07 night log

5/27/07 UT

April 9, 2008 NGS Engineering

Goals

The Palomar AO system has recently undergone a significant refurbishment. In the 4 months since November 29, 2007, we have:
  • Recoated the AO relay flats and OAPs, and repolished and recoated the DM.
  • Realigned the AO relay to provide a focus suitable for P1640 and SWIFT.
  • Mounted FM3 on a removable kinematic base.
  • Modified the PHARO mounting cradle to move PHARO forward 4.5".
  • Modified the AO enclosure and added a PHARO FM3 enclosure.
  • Installed a new AO stimulus, with 594nm laser source.
  • Installed a new motor controller for Aerotech stages.
The purpose of this engineering night is to demonstrate the readiness of the refurbished system for NGS-AO science, and to characterize its performance.

Personnel schedule

Planning to be present on 4/9/08 (local): Angione, Baranec, Bouchez, Burruss, Roberts, Troy.
If night is clouded out, Bouchez will stay on for start of observing on 4/10/08.

Procedures and test plans

Results

May 18, 2008 NGS Engineering

Goals

While basic checkout and calibration of the NGS-AO system were successfully accomplished on April 9, 2008, performance tests were not possible due to clouds and poor seeing. The primary goal of this additional NGS engineering night is to complete the performance characterization of the NGS-AO system after the winter 07/08 optical bench relayout. A secondary goal is the testing of a new iterative reconstructor by L. Lessard and D. MacMynowski.

Personnel schedule

Planning to be present on 5/18/08: Bouchez, Lessard, Roberts, MacMynowski.

LGS Diagnostic Benches

by Anna Moore on behalf of the LGS team (COO, JPL and Univ. of Chicago)

Update ppt 040909 by Anna Moore and Hal Petrie

There are two laser diagnostic benches in development. The first will reside in the coude room therefore measuring properties of the laser as it directly leaves the laser enclosure. The second will reside at the prime focus of the 200" Hale physically attached to the mirror cell of the laser launch telescope (LLT). The LLT bench will measure properties f the laser immediately before collimation and subsequent injection into the sky. The laser diagnostic benches are fed by the Chicago sum 589nm laser and provide the following functionality (1) energy per pulse at coude and at prime focus (2) shear plate collimation at coude (3) near and far field profiles at coude and at prime focus and (4) provide a 10 by 10 wavefront map at prime focus. In addition the LLT diagnostic bench must (5) incorporate the quadrant cell detector Q3 and accessories (6) incorporate the fast steering uplink tip/tilt mirror M5 and (6) incorporate a sky viewing camera with 3 modes of operation that is used to boresight the LLT to the 200inch Hale telescope.

GigE? communication speed is designed into the system linking the benches to the control computer with a 1000BaseT connection. It is hoped that this is adequate enough to provide realtime transfer of analog images from the many (6 or more) CCIR cameras.

General notes and analysis of LLT collimation and performance

  • Most recent sky test results (24 Aug, 2007 UT)
    • Seeing was stable, 0.5-0.6" FWHM in V.
    • After careful collimation, star images were 1.9" FWHM in LLT Pulnix, using RG610 filter (2.9" FWHM with no filter).
    • Laser spot, observed with AO acquisition camera immediately after, was 2.5" FWHM, highly comatic (diamond ring appearance).

Preliminary Results

... and 15s after impact. No obvious detection of an impact ejecta plume.

Palomar AO movie of the LCROSS impact (19 Mb MPEG)

Contact Information

Schedule (Times UT, updated 10/6/09)

  • ~02:00 Spacecraft separation
  • 08:30 Acquire Cabeus crater; determine best feature to use for AO lock
  • 10:30 Acquire 1st set of sky background frames
  • 11:00 Begin impact imaging sequence
  • 11:31:19 Centaur impact
  • 11:35:45 Shepherding spacecraft impact
  • 11:50 End impact imaging sequence, acquire 2nd set of sky background frames
  • 14:00 NASA ARC press conference (submit graphics by 12:30)

Observing Plan

Our goal is to image the evolution of the LCROSS debris plume at the highest possible spatial resolution. We plan to use the Palomar Adaptive Optics system to lock on a bright lunar feature, probably a crater wall or mountain peak, near the predicted impact location. Full AO correction should provide spatial resolution of ~0.1 arcseconds (180 meters at Cabeus crater) across the 40 arcsecond (71 km) field of view of the PHARO near-infrared camera.

The debris curtain is expected to expand at ~150 m/s, reaching maximum brightness after ~60s at a diameter of ~20 km. We will acquire 1.4s integrations every 2.8s, thus providing a ~40 frame movie of the expanding debris plume during its highest density phase. We will observe at K band (2.1 microns), to maximize AO correction and sensitivity to large particles.

We have allocated 2 hrs (8:30-10:30 UT) to locate Cabeus crater and test surrounding features for that providing the best AO correction. We will then offset to blank sky to acquire bias/background frames, and begin our impact imaging sequence at 11:00 UT. We intend to continue the image sequence through impact and for at least 15 minutes after Centaur impact.

******************************************************************************************
Column meaning:
 
TIME

  Prior to 1962, times are UT1. Dates thereafter are UTC. Any 'b' symbol in
the 1st-column denotes a B.C. date. First-column blank (" ") denotes an A.D.
date. Calendar dates prior to 1582-Oct-15 are in the Julian calendar system.
Later calendar dates are in the Gregorian system.

  The uniform Coordinate Time scale is used internally. Conversion between
CT and the selected non-uniform UT output scale has not been determined for
UTC times after the next July or January 1st.  The last known leap-second
is used over any future interval.

  NOTE: "n.a." in output means quantity "not available" at the print-time.
 
SOLAR PRESENCE (OBSERVING SITE)
  Time tag is followed by a blank, then a solar-presence symbol:

        '*'  Daylight (refracted solar upper-limb on or above apparent horizon)
        'C'  Civil twilight/dawn
        'N'  Nautical twilight/dawn
        'A'  Astronomical twilight/dawn
        ' '  Night OR geocentric ephemeris

LUNAR PRESENCE (OBSERVING SITE)
  The solar-presence symbol is immediately followed by a lunar-presence symbol:

        'm'  Refracted upper-limb of Moon on or above apparent horizon
        ' '  Refracted upper-limb of Moon below apparent horizon OR geocentric
             ephemeris
 
 R.A._(ICRF/J2000.0)_DEC =
   J2000.0 astrometric right ascension and declination of target center.
Corrected for light-time. Units: HMS (HH MM SS.ff) and DMS (DD MM SS.f)
 
 a-mass =
   Relative optical airmass at target center point. Topocentric EARTH sites,
ABOVE HORIZON ONLY.  Unitless.
 
 APmag S-brt =
   Target's approximate apparent visual magnitude & surface brightness. For
planets and satellites, values are available only for solar phase angles in the
range generally visible from Earth. This is to avoid extrapolation of models
beyond their valid (data-based) limits.  Units: NONE & VISUAL MAGNITUDES PER
SQUARE ARCSECOND
 
 Ang-diam =
   The equatorial angular width of the target body full disk, if it were
fully visible to the observer.  Units: ARCSECONDS
 
 Ob-lon Ob-lat =
   Apparent planetographic ("geodetic") longitude and latitude (IAU2000 model)
of the center of the target disk seen by the OBSERVER at print-time. Light
travel-time from target to observer is taken into account. Latitude is the
angle between the equatorial plane and the line perpendicular to the reference
ellipsoid of the body (e.g., reflects body oblateness). Positive longitude
is to the west.  Units: DEGREES
