Young’s two slits interference of discrete double light source is numerically simulated,and the curve of visibility, curve of light distribution and interference pattern are solved with different type of line and line width.

The light distribution of pointolite, interference fringe and its characters are discussed by theory of interference of light on the condition of plate thickness being non uniform.

Staring from Fresnel diffraction integral,we deduced the optical intensity distribution in the Fresnel zone of the diffraction field of the annular-aperture lens axicon.

This article makes theoretical analysis on the relationship and distinction between Bessel and Bessel-Gauss beams,the optical intensity distribution at any propagation plane of ideal Bessel beam and the Bessel-Gauss beam,and the effect of the beam waist and the cavity length L on the Bessel-Gauss beam were simulated.
