Experimental results for the double passage imaging of an optically rough object are presented. The approach is based on a confocal arrangement using two coherent, focused beams and polarization manipulation. An appreciable improvement in image quali

The possibility of improving the image quality of a coherently reflecting object, viewed through a randomly inhomogeneous medium, is investigated theoretically. Three cases of coherent illumination of the object by a plane wave are considered: illumi

It has been predicted theoretically that the combination of spatial filtering together with double-passage illumination and viewing of a deterministic object leads to an improvement in image quality. The results of experimental investigations of this

We present laboratory results for measurements of the four-point coherence function of a spherical wave in the region of coherence enhancement after backscattering through turbulence. Experimental results are compared with the theoretical predictions

We report what are to our knowledge the first experimental results of coherence enhancement that use polarization to separate coherent and incoherent paths.

The results of ship-borne measurements (16-th expedition of research vessel "Academician Nesmejanov") of signals from navigation satellites TRANSIT at two frequencies (150 and 400 MHz) are presented. It was discovered that besides the basic modulatio

We present experimental results of active imaging of an optically rough object obscured by turbulence. Our approach is based on an arrangement using a coherent focused beam and multiaperture receiving system. An appreciable improvement of image quali

Experimental observations of the coherence enhancement phenomenon are presented and described. We have illuminated an optically rough moving target through turbulence using two mutually coherent point sources and observed the interference of the scat

The results of laboratory measurements of the spatial distribution of the four-point coherence function (fourth moment) of a spherical wave are presented. Using a special interferometric system we have illuminated a rough surface through turbulence w

We describe experimental investigations of the confocal microscopy method for imaging optically rough objects through turbulence. We have compared the potential of one- and two- lens illumination/receiving systems for the situations when illumination
