一种激光纹影仪的光学特性
Optical characteristics of laser schlieren instrument
摘要
本文采用带有中央相位跃变间隔的光栅作为空间滤波器,并用希尔伯特变换对这种激光纹影仪的光学特性进行了分析.实验结果与离散希尔伯特变换的计算结果相符.同时给出了应用实例.
Abstract
The Ronchi grating bearing 180°-shifting phase is used, in this paper, as a Hilbert transform filter. Some experimental results are presented and the optical characteristics of this kind of laser schlieren instrument are analyzed.
