Schematic of an improved image transmission system using phase conjugation and magnification of the transmission wavefield, where a retroreflector is placed at R0, PC is a phase conjugator, PD1 and PD2 are phase distorting layers. Vectors R, S, Y, and X represent 2-D coordinates.

Experimental system. A pinhole (PH) was used instead of the retroreflector. An artificial phase distorting layer T was made of a single 0.5-mm thick plastic plate, whose thickness is spatially random with an average phase variation of ∼3λ. An analyzer A was used to improve the SNR. The focal length L1 is 200 mm, and that of L2 is 50 mm. A 6-kV/cm electric field was applied to the BSO crystal.
