摘要

本文提出利用太赫兹偏振测量来无损测量聚合物产品的内部残余应力。为了验证所提方法的有效性，使用差频光源、线栅偏振器和 FMB 二极管开发了太赫兹偏振测量系统。实验分析证实，太赫兹偏振与聚合物取向和作用力之间存在相关性，并利用所开发的系统测量了这些关系。最后研究了太赫兹偏振因子与残余应力之间的关系，证实我们开发的测量系统可以实现聚合物内部残余应力的无损定量评估。

Development of residual stress evaluation method for polymer products using THz polarization measurement

This paper proposes to utilize THz polarization measurement to nondestructively measure internal residual stress in polymer products. To verify the validity of the proposed method, a THz polarization measurement system was developed using a difference frequency light source, wire grid polarizers, and FMB diodes. Experimental analyses confirmed that THz polarization had a correlation with polymer orientations and the applied force by measuring these relationships with the developed system. The relationship between THz polarization factor and residual stress was finally investigated, which confirmed that our developed measurement system can achieve nondestructive and quantitative evaluation of the internal residual stress in polymer.
