Abstract

A portable, rugged, inexpensive shearing interferometer is described and evaluated. Originally intended for application to plasma and flow analysis, it is also a suitable instructional aid. The shearing is obtained by the offset of the reflection from the first surface of a mirror relative to the reflection from the second surface when the mirror is set at an angle to the illuminating beam. The sensitivity is equivalent to that of a schlieren system. However, no schlieren quality components are involved and there are no critical adjustments or dimensions.

摘要

本文描述并评估了一种便携式、坚固耐用且价格低廉的剪切干涉仪。该干涉仪最初旨在用于等离子体和流动分析，同时也是一种合适的教学辅助工具。当镜子与照明光束成一定角度设置时，通过镜子第一表面的反射相对于第二表面的反射的偏移来实现剪切。其灵敏度与纹影系统相当。然而，该干涉仪不涉及纹影质量的组件，也不存在关键的调整或尺寸要求。
