WFS FOV averaging on phase screen at 5km


WFS 1 (FOV: 20x20")
WFS 2 (FOV: 11x11")


WFS 3 (FOV: 11x11")
WFS 4 (FOV: 11x11")

Difference in WFS phase due to FOV averaging
(from 5km phase screen)


WFS 1 phase FOV=0 and FOV=20"
WFS 2 phase FOV=0 and FOV=11"


WFS 3 phase FOV=0 and FOV=11"
WFS 4 phase FOV=0 and FOV=11"





FOV_0 = 0" ---------------------------- FOV_0 = 40" ---------------------------- Phase screen
