The features of the Talbot effect using the phase diffraction gratings have been considered. A phase grating, unlike an amplitude grating, gives a constant light intensity in the observation plane at a distance multiple to half of the Talbot length Z

Theoretic and experimental studies of the Talbot effect for aberrated optical wave is performed. Talbot images of the quasi-periodic mask restored by aberrated optical wave are predicted to appear, and scale factors are obtained.

A holographic wavefront sensor based on the Talbot effect is proposed. Optical wavefronts are measured by sampling the light amplitude distribution with a two-dimensional (2D) precorrected holographic grating. The factors that allow changing an angul

Application of the Shack-Hartmann sensor with holographic lenslet array is offered for wavefront aberrations measurements in speckle field. The main feature of the method is that the tested wave front can be compared with the arbitrary wave front pre

Physical constraints and peculiarities of the wavefront sensing technique, based on the Talbot effect, are discussed. The limitation on the curvature of the measurable wavefront is derived. The requirements to the Fourier spectrum of the periodic mas
