Paper Abstract

Ever-increasing volumes of data recording and data processing require minimization of archive storage sizes, which can be efficiently achieved by increasing the density of optical recording. Therefore, in the framework of the present study, it is certainly of interest to explore the possibility of using specklograms recorded with a changed scale for implementing such a task in data array processing as image subtraction. Since specklograms are recorded without any specifically formed reference beam in multimode laser radiation, they display great potential for processing the optical data received from diffusely scattering objects in natural conditions.
