Double passage imaging of partially coherent objects through turbulence: experimental results

摘要

Abstract: It has been shown in previous work that double passage imaging combined with spatial filtering leads to an improvement in the quality of the time-averaged image obtained from coherently reflecting objects (mirrors) which are placed in turbulence. In this paper, the results of experimental investigation of the imaging of partially coherent objects are presented. We have demonstrated that double passage imaging leads to an improvement in image quality only for objects whose correlation scale is larger than the coherence radius of the illuminating radiation. !17
