Research on Stitching Algorithm of Large Aperture Optical Elements Piecewise Measurement Data

Abstract:

Due to the range of the measuring system is limited in the measurement of large aspheric optical elements, test is hard to be once fulfilled, so coordinate measurement based on multi-section stitching is proposed, and the least square mathematical model of large aperture optical elements multi-section stitching is built. Moreover, the profiler Talysurf PGI 1240 made by Taylor Hobson company is used for study. The result shows that, the method is suitable for multi-section data stitching for large aspheric optical elements, and possesses many advantages, such as fast speed, high accuracy and strong operability, etc.
