Abstract:

An experimental method of processing of an optical signal transmitted through a stochastic medium is proposed. The method is reduced to modulation of a received radiation with a phase knife–edge plate incerted into a telescopic system. By way of example, the experimental results on detecting a laser beam scattered by optically dense screens are given. It is shown that the direction toward the radiation source is determined quite reliably at optical thicknesses t< 12 , with a coherent radiation intensity being half as many as the scattering background.
