Equivalent Fresnel number for regular triangle aperture;

Based on the beam coherence-polarization matrix and the propagation law, the polarization properties of partially coherent flat-topped light beams diffracted through a regular polygonal aperture are studied systematically.

Using the relations between Hermite and Laguerre-Gaussian(LG) modes and expanding the window function of two-dimensional rectangular hard-edged apertures into a finite sum of complex Gaussian functions,the propagation of complex-argument Laguerre-Gaussian beams through a paraxial optical ABCD system with a rectangular hard-edged aperture is studied.

By using the method of expanding the aperture function into a finite sum of complex Gaussian functions, approximate closed-form propagation equations of TMn0-Gaussian beams diffracted by hard-edged parallelogram apertures are derived.

Influence of hard-edge aperture on the spectral switch of polychromatic vector beams;

To study the influence of hard-edge apertured and misaligned Lohmann s optical system on fractional Fourier transforms,the flat-topped multi-Gaussian beam model was adopted to simulate hard-edge apertures.
