Abstract

We introduce image quality criteria for organizing feedback control in adaptive imaging systems. These image quality criteria are dependent on the Fourier spectrum of the image and can be obtained optically with a coherent optical system. Digital processing of the image plane intensity distribution is not required. We present experimental results, along with corresponding numerical simulations, that demonstrate the potential effectiveness of these criteria for adaptive correction of phase-distorted extended-source images.
