Abstract

Optical oscillator with holographic mirror formed by external signal wave (fig. 1) is considered to be one of the prospect and effective PC-corrector being used in different laser systems. When one needs to reconstruct information about object wave distorted by transmission function of some random transporting medium (for instance, of multimode fiber) one has to deal with the hologram recorded by two waves both of them being speckled ones. In this case, the traditional holography (Gabor’s holography) based on the principle of “supporting"(when one of the two writing waves is considered to be plane wave against the background of other, I₁ E₃ =const E₃) turns out to be practically unacceptable.
