Abstract

It is shown first that, in the one-way image-transmission system using a pointlike reflector and four-wave mixing, which was proposed by the authors, the compensation for a thin-layer turbulence depends on the longitudinal correlation of the turbulence in addition to the lateral correlation; that is, it also depends on the distance from the transmission plane to the turbulent layer. Then two methods are presented that significantly increase the correlation equivalently and thus improve the characteristics of the system. One method is based on the adaptive focusing of the transmitting image field around the turbulence, and the other method is based on the use of multiple reflectors on the observation plane. Theoretical descriptions, modifications of the system, and numerical examples are given.
