Separating and Image Processing of Multi-Frame Dynamic Isopachics and Isochromatics
多幅动态等和线及等差线的分离和图象处理

A new and effective method of sandwich photocarrier fringes is presented to separate principal stresses for both static and dynamic holographic photoelasticity, especially for multi-frame recording. It is succesful to use digital image processing in dynamic holographic photoelasticity.
