Paper Abstract

The possibility of fulfilling integral transforms of coherent light fields by phase diffraction gratings was studied. To realize the family of Hilbert integral transforms in a prescribed diffraction order, a binary grating consisting of two parts of equal width but different cross size-to-period ratios of rectangular grooves was suggested. Grating geometries permitting the Hilbert transform with the maximum intensity concentration to be performed in a given diffraction order were described. The mapping effect of the integral beam images in Fresnel zones of the suggested phase gratings was discovered. The observation conditions and possible ways of using the effect are also outlined.
