TLDR
In this article, a two-dimensional theory of the Lau-Talbot-Moire effect by means of an Ambiguity Function is presented, and it is found that the Lau fringes are dependent upon the grating rotation angle, and the fringe pattern at the observation plane is influenced by two important factors, the coherent diffraction factor and the Lau Moire interference factor.About:

Degree of coherence: a lensless measuring technique.
TL;DR: A technique for measuring the degree of coherence that is based on the self-imaging phenomenon is presented, which is lensless, has multiplexing capabilities, and can work with high light throughput.

Grating pseudo-imaging with polychromatic and finite extension sources
TL;DR: In the analysis presented, different imaging regimes are found and related to the parameters which characterize the double grating system, and pseudo-image process analogous to Talbot effect appears only by monochromatic and plane illuminating wavefront.

Lau effect and beam collimation
TL;DR: In this paper, the rotation sensitivity of Lau fringes depends not only on spatial coherence of the illumination used but also on its convergence or divergence, and this finding could be usefully applied to beam collimation and focal length measurement.

Analysis of general double periodic structure diffraction phenomena based on the ambiguity function
Jinhong Tu,Li Zhan +1 more
TL;DR: In this article, a general configuration made up of two arbitrary periodic structures and a thin lens under partially coherent illumination is presented, where the separation of these elements along the optic axis can be adjusted to meet some special requirements (system conditions) to form a meaningful pattern on the observation screen.

Achromatic self-imaging with finite extension light sources
TL;DR: In this article, an intuitive interpretation of the achromatic behavior in terms of optical paths is presented, which is useful for a wide range of photonic and technological applications such as optical encoders, interferometry, optical inspection techniques, structured illumination, microscopy, etc.

Ambiguity function in Fourier optics
TL;DR: In this article, a theory of Fresnel diffraction and Fourier optics results, involving merely coordinate transformations of the independent variables of the aperture ambiguity function, is derived in terms of certain moments of the amplitude of the incident wave.

Partially coherent diffraction effect between Lau and Talbot effects
TL;DR: In this article, the diffraction effect of gratings under partially coherent illumination generated by a source slit was studied and the experimental results were in good agreement with the theoretical intensity distributions.

Role of spatial coherence on the rotation sensitivity of Lau fringes: an experimental study
TL;DR: It is observed that the rotation sensitivity of Lau fringes varies in a well-defined manner as a function of the spatial coherence of the light used, and it appears that the Lau effect need not be associated with an incoherent optical field.
