本文从标量衍射理论出发,在一定的近似条件下,写出了非点光源情况下全息光学元件的点扩散函数表示式,讨论了光源角宽度对全息光学元件分辨率的影响。
In this paper, based on the scalar diffraction theory, under certain conditions, the expression of point spread function of holographic optical element under non-point light source is written out. The influence of light source angular width on the resolution of holographic optical element is discussed.
