Talbot and Lau effects on incident beams of arbitrary wavefront, and their use.


Both the Talbot and the Lau effects of Ronchi and binary phase gratings on an incident wavefront of arbitrary wavefront are discussed. General and analytic solutions are obtained in terms of the Fresnel diffraction theory. Numerical simulations and supporting verification for Gaussian beams are demonstrated. It is found that the distortion of the self-image… (More)
