Study on Accurate Phase-Demodulating of Phase-Approaching of Projected Grating Used in 3D Detection
The problems are analysed in practical 3D detection by phase approaching of projected grating that frequency-moving in frequency domain and the correspondence between measured surface and reference plane have great effect on the accuracy of phase-demodulating. An appropriate method for avoiding frequency-moving and a new concept of full-field reference plane are proposed. Their perfect perfomance has been verified.
