OPTICAL-SIMULATION OF PHASE-DISTORTED IMAGING-SYSTEMS - NONLINEAR AND ADAPTIVE OPTICS APPROACH

We discuss a technique based on nonlinear and adaptive optics for simulation 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 distribution. The intensity pattern is converted into a spatially varying thin 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 mirror with computer control is used for simulation of large-scale phase distortions.
