Abstract
Original experiments on measurements of the coherence length of diffusely s cattered CW laser beams using GaAs adaptive photodetectors based on the pho to-EMF effect are presented. Simplicity of the configuration, capability to detect aberrated speckle-like wavefronts with high signal-to-noise ratio, and potentially high speed of operation make this configuration potentially useful for Optical Coherence Tomography and Laser Ranging.
