Reconstructing spatial phase distributions and object images from speckle intensity patterns of the diffraction field

About Holographic (Interferometric) Approach to the Primary Visual Perception

“…), and second, the scattering layer or all optical system must be fixed during processing. Moreover information capacity of such processing must be very large (more than several tens of gigabits per second), while it is known that in optical nerve it is limalgorithms can be found in [42][43][44], and so here we consider their physical sense and the necessary conditions to implement them.…”

“…Restoring the original image in this optical model containing the scattering medium can be achieved by several methods, developed in coherent optics [40], namely, by matched filtering processing (phase conjugatio nlinear methods of holographic speckle interferometry [42][43][44][45][46]. Despite the fact that matched filtering processing is the most accurate method of image reconstruction in a heterogeneous environment; the difficulties of its implementation in visual apparatus are obvious.…”
