Paper Abstract

A new birefringent common-path interterometer with an automatic data-processing system is presented fortesting large convex spherical surfaces. With this interferometer, it is easier to eliminate system errors and to achieve quite accurate measurement. The precision of the system is about λ/50 with an accuracy of about λ/10.
