Further Information
We introduce a nonlinear optical technique for the creation of small-scale phase distortions in coherent optical systems. This technique uses the nonlinear response of a liquid-crystal light valve placed in a 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 a second liquid-crystal light valve. A chaotic phase distortion is then introduced into the output image of a coherent imaging system by propagation through the phase screen.
