Paper Abstract

The scatter plate interferometer a simple structure and is very conventient for measuring the surface errors of a concave mirror. In this interferometer, unlike all the others, there is no one-to-one point correlation between the mirror to be tested and the scatter plate which acts as a beam splitter. Using this feature, we show that a scatter plate interferometer is more stable than any other interferometer. In addition, a new convenient method, which can realize the null test of aspheric surfaces, is proposed by some modifications of optical setup, without using any special optical elements.
