Intensity distribution of converging spherical waves passing through an annular aperture;

The spectral behavior of polychromatic spatially fully coherent light diffracted by an annular aperture in the far field is studied.

The singularity changes and spectral behavior of polychromatic spatially fully coherent light diffracted by an annular aperture in the near field were studied.

Study on focusing characteristics of serrated aperture apodizer in high energy laser system;

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.

Based on the fact that circ function can be expanded by an approximate sum of complex Gaussian functions with finite numbers,the analytical formula for the axial intensity distribution of a partially coherent Gaussian Schell model (GSM) beam through a circular lens with finite aperture was derived.

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.
