A new optical path presented in this paper combines the holographic photoelasticitywith the holographic interferometry. One of two holograms reconstructs the isopachic fringepattern of the light transmitted through the model, and the other recorded by the reflectedlight from the front surface of the model reconstructs the reflective isopachic fringepattern. The two holograms are recorded simultaneously by means of a holographic plate.We have deduced our conclusion from the theory that the two fringe patterns depend on thethermal expansion and the sum of principal stresses respectively. Therefore, the temperatu-res and the sum of principal stresses on the model can be independently determined bythese two isopachic patterns. Then according to the isochromatics the two principal stressescan be separated from each other. As the method described has a high sensitivity, some ofthe shortcomings of traditional thermophotoelastic methods can be compensated or overcomeby using this method.

本文提出一种新的光路,该光路将全息光弹性法和全息干涉技术结合起来,在一张全息干板上记录热光弹性模型透射等和干涉条纹的同时,还记录模型前表面反射的等厚干涉条纹。理论推导证明:两组条纹独立依赖于热膨胀和主应力和,从而可求模型上各点的温度及主应力和,再利用等差条纹还可分离各点的应力。此法灵敏度高,能弥补和克服传统热光弹性的不足。
