The effect of curvature change of a mirror surface on the removal function of ion beam figuring was explored.A new higher precision figuring method for a highly steep off-axis asphere was proposed by using a correction matrix to calculate the removal

As the surface shape of a reflection mirror is different from the target shape at the end stage of the grinding process,and the profilometers and common interferometers can not measure the surface error exactly,this paper proposed a method to measure

A new test method based on a Computer-generate Hologram(CGH) was presented for precisely testing off-axis aspheric surfaces and aligning the optics in tests.In this method,off-axis aspheric surfaces were tilt-translated and tested as an on-axis freef

Circular Subaperture Stitching Interferometry(CSSI) and Annular Subaperture Stitching Interferometry(ASSI) were expounded to realize the test of large aspheric surfaces without the null optics.The theories and principle of the technique were analysis
