Abstract

A correlation is established experimentally between the real “faceted” structure of the cutting area of a blade according to electron microscopy data and the spatial quantization of an image of the recorded speckle field (upon the maximum compression of the recorded information to logical zeroes and ones) in coherent optical analyses of the diffraction effect at the blade edge. This correlation may prove useful for solving the inverse technical problem (with equally justified variants of concepts for the theoretical modeling of a specific situation).
