Paper Abstract

In this paper we propose the new method of nondestructive checking, based on application of the fractal masks photographed through the objects under study. Coherent optical image processing of the fractal masks allow to receive the separate information about components of the refractive index gradient and phase discontinuities. The power of high spatial frequencies of the fractal mask spectrum is three times greater in comparison with spectrum of regular mask. The analysis of results of the inverse Fourier transform of the distorted spectrum of regular and fractal masks shows that the fractal mask is more sensitive and allows to obtain the value of distortion of the initial object more precisely.
