Paper Abstract

A portable phase-shifted interferometer with multiply usages is described. Several techniques are studied and used in this interferometer. In order to test an optical piece with obscuration or irregular edge, we study the seed-algorithm for wavefront reconstruction. For testing a corner cube reflector (CCR), we investigate the model to calculate its exit wavefront and angle error. To measure the figure of a convex or concave spherical surface, we develop a series of reference transmission spheres.
