Dynamic Phase Measurement Based on Two-Step Spatial Carrier-Frequency Phase-Shifting Interferometry

A dynamic phase measurement method based on a two-step spatial carrier-frequency phase-shifting (TS-SCFPS) technique is proposed. First, by the subtraction operation between a pair spatial carrier-frequency interferograms with a certain phase shifts, which are captured by dual-channel interferometry...
