OPTICAL-SIMULATION OF PHASE-DISTORTED IMAGING-SYSTEMS - NONLINEAR ANDADAPTIVE OPTICS APPROACH

We discuss a technique based on nonlinear and adaptive optics for simu lation of phase-distortion effects in imaging systems. This technique uses a nonlinear two-dimensional optical feedback system to produce a controllable spatially and temporally varying chaotic intensity distri bution. The intensity pattern is converted into a spatially varying th in phase screen using an optically addressed spatial phase modulator. A chaotic phase distortion is then introduced into an imaging system's output image by propagation through the phase screen. A deformable mi rror with computer control is used for simulation of large-scale phase distortions.
