چکیده
Simultaneous phase-shifting interferometry (SPSI) can simultaneously obtain multiple phase-shifted interferograms and realize the dynamic wavefront measurement with use of a algorithm. From respect beam-splitting technique phase shift achievement units, research progress on spatial shifting approaches for SPSI systems are classified summarized, key problem affecting technology is discussed. To ensure accuracy, it necessary to perform accurate position registration multi-channel before implementation algorithm, so, methods also reviewed. This review expected prompt related fields interferometry.

Phase shifter calibration in phase-shifting interferometry.
This paper describes some practical methods to calibrate the phase shifter in phase-shifting interferometry (PSI). The phase shifter used in the experiment is a piezoelectric transducer (PZT) that has a nonlinearity of <l%. Using the quantitative method described in this paper, the repeatability in the measurement of the phase-shifting angle is ̃9.046 rms, and the 3σ value is 0.139. A calibratio...

This paper describes a technique that combines ideas of phase shifting interferometry (PSI) and two-wavelength interferometry (TWLI) to extend the phase measurement range of conventional single-wavelength PSI. To verify theoretical predictions, experiments have been performed using a solid-state linear detector array to measure 1-D surface heights. Problems associated with TWLPSI and the experi...
متن کاملAccurate phase-shifting digital interferometry.
In phase-shifting interferometry experiments, the accuracy of the phase shift is a major issue. Many experimental and data analyses are done to cancel phase-shift errors inherent to the modulation techniques used. We propose to remove most of the phase-shift error by recourse to a frequency-shifting method. This approach can be applied to both holography and interferometry. We validate the idea...
