  • To realize the high accuracy measurement of optical surfaces by a phase-shifting Fizeau interferometer, a synchronous acquisition phase-shifting system in the interferometer was established, and an accurate phase shifting method was researched. First, the composition and working principle of the phase-shifting system were introduced. Then, the velocity of PZT phase shifter during measurement was calculated. Since there exist defocus errors as well as speed-up and speed-down steps during phase shift, the moving process of phase shifter was detailedly designed. Finally, the phase shifter was calibrated. A verified experiment was carried out on the modified interferometer, and it shows that the RMS simple repeatability is /11 340. Comparative measurement was also carried out with two same components between the modified interferometer and the Verifire XP/D interferometer(Zygo company), and the RMS difference is about 0.9 nm. It can be seen that the repeatability and accuracy of this phase-shifting system and phase-shifting method have satisfied the requirement of nano-scale form measurement, which can provide references for developing high accuracy phase-shifting interferometers.
