Paper Abstract

A new method of subaperture stitching based on Hartmann-Shack wavefront sensor is presented to solve the testing of large-aperture optical systems and components. The measured full aperture is divided into several area apertures, a Hartmann wavefront sensor is used to sense the wavefornt informations of each area aperture one by one. Modifying factors of errors are obtained by the overlapping area between two adjacent area aperture, the wavefront information of full aperture which can get by stitching algorithm and wavefront reconstruction algorithem . Proving in theory, simulation and testing experiment are given in this paper, the results shows the effectiveness of the method. It is simple and faster compared with other wavefront stitching algorithm, which can be used for testing the large optical systems and components.
