摘要
提出了一种基于光栅衍射原理的椭圆反射式波带片(ERZP)光线追迹算法,分析了ERZP的衍射聚焦和能谱分辨特性。基于该算法,将ERZP光线追迹模块添加到光学仿真软件X-LAB中,使之具有了计算量小、效率高等优点,这对含有ERZP光学系统的设计和数值模拟具有重要意义。
Abstract
A ray-tracing algorithm of the elliptical reflection zone plate (ERZP) based on the grating diffraction theory is proposed, and the diffractive focusing and spectrally resolved properties of an ERZP are analyzed. Based on the proposed algorithm, the ERZP ray-tracing module is added in the optical simulation software X-LAB, which makes it possess the advantages of small computational cost and high efficiency. This is of great significance to the design and numerical simulation of optical systems with an ERZP.
