Abstract
The effect of phase shifting error in phase shifting interferometry is investigated. A new algorithm for eliminating the effect is presented. The computer simulation and experiment results show that the phase shifting offset should be (pi) when two-set-bucket error compensating method is used, and this method has gotten better results than the original four bucket algorithm.
