| Abstract: | Of the different shape measurement methods and the phase analysis techniques, optical profilometry for the diffused reflection objects can be classified into two groups, namely direct triangulation and grating projection phase measurement method. This paper mainly introduces grating projection as one kind of phase measurement method. The measurement principle of grating projection method and the key techniques, such as Fourier transformation method, phase unwrapping and system calibration, are given. Some currently popular research subjects and future possible topics are presented. |

| Keywords: | optical profilometry grating projection phase measurement phase unwrapping system calibration |
