Paper Abstract

Comparative simulations are designed to evaluate the noise suppression performance of three typical phase shifting algorithms under different testing environments. The results show that random phase shifting algorithm is robust under different level of noise and has higher testing accuracy than conventional normal steps phase shitting algorithm while it’s computationally low. Guidelines are given to choose a proper PSI algorithm under a certain testing environment with noises.
