摘要:	This investigation accurately measures the relationship between applied voltage and the displacement of a piezoelectric transducer device both by analyzing phase shifting interferometry algorithms and using a Twyman-Green interferometer. Simulations are performed to calculate unknown phase shifts, especially around pi/2 and 3 pi/2. It is indicated that the Hariharan algorithm is indeed an effective phase shifting interferometry algorithm.
