simple AO filtering model using Fourier analysis simulates WFS integration, delay, noise (as a function of spatial frequency)

Open loop model

AO simple filter is modeled by several 2D maps in spatial frequency: aosf_noise : noise per spatial frequency aosf_mult : signal throughput per spatial frequency aosf_gain : loop gain to be applied per spatial frequency

< WFS exposure time

< time delay between wavefront sensor measurement (end of exposure) and DM correction [sec]

wavefront correction buffer to implement time delay

< time it takes for DM to move

< turbulence channel
