摘要：

Measure the measured-object by phase profilometry of a projected grating image and get image information of measured-object in this text. The problem of spectrum aliasing is expatiated and bring forward Principle of Two Steps Phase-Shifting to eliminate the reflection of background luminosity so it is easy to distill useful information and unwrapped phase on the base of this way.
