<title>Analysis of the fundamental measuring error of aspherical surface by shearing interferometer</title>

Abstract: In the methods to test an aspherical optical surface , sheering interferometer is a testing instrument by which the wavefront of the surface tested is split apart into two and then interference fringes can be formed without demanding a standard reference aspherical wavefront ,so that it is an effective method of testing the aspherical surface getting rid of difficulties of making a standard surface and the errors caused when other instruments are used.However , if the sheering interferometer is applied to test… Show more

“…This difference in ''mapping" between the test and reference rays in the viewing system creates an additional OPD contribution that depends upon both the shape and misalignment of the test surface. This mapping-induced OPD error can be thought of as a shear of the test wave-front and reference wave-front in the exit pupil of the viewing system [9,10].…”

“…Along with the application of aspheric surfaces, methods for testing aspheric surface have been put forward in succession. Of all, typical ways such as lens compensator 1,2 , computer-generated hologram (CGH) 3 , sub-aperture stitching 1 and interference testing 1 are in common use, where especially, interference testing is used a lot because its simple and convenience. While testing aspheric surfaces by interference testing, the reference wavefront incidences on the aspheric surface, if in ideal case, the incident ray will be reflected in the same way by aspheric surface.…”
