New method is proposed for solving the problem of image analysis, comparison and invariant recognition. This method is based on Fresnel transform of the image, comparing the phase portrait of Fresnel pattern and following calculating a level of likeness of phase portraits of unknown and primery standart images. The method theory based on statistical description of optical signals is considered. The method study in relation to interferences as well as method connection with optical field coherent characteristics are shown. Method has sufficient advantages in signal/noise ratio in image recognition process and passesses best accuracy in image coordinates definition in comparison with known correlation methods.
