An Interferometric Method for Determining Stress-Optical Constants

摘要: 本文介绍平板干涉法测定材料应力光学常数的原理与过程,并给出同一有机玻璃材料用干涉法、全息法、双屏法测定结果的对比。

Abstract: This paper introduces the principle and procedure of an interferometric method for determining the stress-optical constants of a specimen material. A comparison of the measured results for a material of polyme-thylme-thacrylate by using the holographic method, the double-screen method and the interferometric method is given.
