Abstract :
Resolution as a function of aperture length in the presence of phase errors is investigated with the aid of the spatial power spectral density. Numerical calculations are made for power spectra thought to be appropriate for phase errors due to atmospheric turbulence. Both Gaussian and uniform illumination are considered, and the results obtained here are compared with those reported by Brown and Riordan [2].
