Shearing Interferometry with Real-Time Polarization Phase-Shifting Technique
Based on the principle of projected grating, a new real-time polarization phaseshift shearing interferometry is proposed and discussed. The method can be used for measuring shapes of 3-D diffuse objects and displacement of large deformation automatically. Some experiments were demonstrated to verify the validaty of the present technique.
