Subtraction of image by spatial filtration of area was restored twice registered scaled specklogram

摘要

All increasing amounts of recording data and data processing requires minimization of sizes of archive memory, which can be effectively reached by raising of optical recording density. Consequently, in the framework of present analysis, central interest is to study a possibility to use speckleograms written with scaling for realizing such tasks in data array processing as subtraction of image. As far as specklegrams are written without any specifically formed reference beam in multiple-mode laser radiation, they display rich optical data processing potential for diffuse reflecting objects in natural conditions.
