应力-光学定律是光弹性力学的基础，也是测量应力的常用方法。然而，其在太赫兹（THz）制度的有效性还没有完全表征。本文研究了单向拉伸应力对聚四氟乙烯（PTFE）样品太赫兹波透射的影响。具体而言，太赫兹时域光谱（THz-TDS）已被用来测量相位延迟的透射太赫兹辐射的不同PTFE应力状态。从测量的相位延迟计算PTFE的折射率的差异。计算的折射率随外加应力线性增长，这可以被认为是在太赫兹频率范围内的单轴应力-光学定律的验证。
The stress-optic law is fundamental to photoelasticity, and has been a prevalent method for measuring stress. However, its effectiveness in the terahertz (THz) regime has not been completely characterized. In this paper, the effects of uniaxial tensile stress on THz transmission through a polytetrafluoroethylene (PTFE) sample are investigated. Specifically, THz time domain spectroscopy (THz-TDS) has been used to measure the phase delay of transmitted THz radiation for different PTFE stress states. Differences in the refractive index of the PTFE are calculated from the measured phase delay. The calculated refractive index grows linearly with the applied stress, which can be considered a verification of the uniaxial stress-optic law in the terahertz frequency regime.
