High-Accuracy Surface Profile Measurement Based on the Vortex Phase-Shifting Interferometry
According to the principle of phase-shifting interferometry and spiral phase characteristics of the vortex beam, this article proposes a method for detecting the surface profile of a transparent object, in which the +1 order vortex beam is generated by a spatial light modulator and is taken as the r...
