Abstract

In this article, a new method is introduced to reconstruct 3D profile from the 2D interferogram of Fizeau Interferometer. By using matrix optics, the interferometric mechanism is analyzed. On this bases, the relationship between the interference pattern and 3D profile is built up by fringe tracing of two interferograms of the object to be tested at two places with a certain separation. Depending on the relationship, the data profile are figured out and the 3D profile is obtained with the aid of computer.
