The phase extraction technique based on the traditional spatial-temporal fringe pattern method is studied, which is perfected by correcting the phase-shift of the phase-shift fringer pattern with a linear carrier frequency. This technique is also applied to the fiber-optic interferometer projection for three-dimensional surface measurements. Compared with the traditional four-step phase-shifting method, overlapping averaging four-frame algorithm, and the advanced iterative algorithm, the phase extraction technique based on the spatial-temporal fringe pattern method can effectively suppress the phase-shifting error caused by phase-shifting inaccuracy of the phase-shifter in the fiber-optic interference fringe projection device and environmental factors. Further, it can eliminate the high-frequency noise caused by factors, including stray light.
