Phantom test of TomographySphericalWave.pro

The "phantom" is a circular shape of 1 micron of phase aberation at 6 km altitude. There are 5 layers (0, 3,6,9,12 km). Tomography was performed using 5 laser (90 km) guidestars in a dice pattern of radius 30 arcsec. The tomography algorithm was told that turbulence was equally distributed among the layers (uniform Cn2 profile)

2nd Phantom test of TomographySphericalWave.pro

The "phantom" is a Gaussian shape of 1 micron of phase aberation at 6 km altitude. The Gaussian shape will make it easier for Hartmann sensors to measure the wavefront since there are no abrupt steps in phase as in the case of a circular disk aberation like the 1st phantom. There are 5 layers (0, 3,6,9,12 km). Tomography was performed using 5 laser (90 km) guidestars in a dice pattern of radius 30 arcsec. The tomography algorithm was told that turbulence was equally distributed among the layers (uniform Cn2 profile)
