Abstract

The use of crossed Babinet Compensator (B. C.) combination as simple and effective device for wavefront sensing and evaluation has been described. This method can be utilized for on line evaluation of the wavefront or the surface errors in situations like active optic s system. Advantages of the method and procedure for the reduction of the B. C. fringe data for the wavefront evaluation are presented in this paper.
