回顾了先进迭代算法的基本概念，并给出了具体的实现过程。通过计算机仿真，对具有帧内和帧间强度变化的真正随机相移干涉图的性能进行了评价。该算法用于测量微电子组件在对流热载荷下的热翘曲时遇到的随机相移。
The fundamental concept of the advanced iterative algorithm is reviewed and a detailed procedure for implementation is presented. Computer simulations are conducted to evaluate its performance for truly random phase-shifted interferograms with intra- and inter-frame intensity variations. The algorithm is implemented for random phase shifts encountered during thermal warpage measurement of a microelectronics subassembly subjected to convective thermal loading.
