摘要 | In order to realize the optical measurement of 150 mm SiC convex hyperboloidal mirror, the traditional Hindle sphere testing, Simpson Hindle testing and aspheric plate testing methods are designed. These methods are compared in accuracy, tolerance, et al.. The Hindle sphere testing is chosen because of higher accuracy, loose tolerance and simple support structure. After grinding and polishing, the surface error is 0.023 (mean square root). In the alignment, a method based on laser tracker and interferometric testing of Hindle sphere is proposed. The sphere mounted retrofeflector of laser tracker is interferometric tested and the positions are measured, which are corresponding to the two geometry focuses of hyperboloidal surface. Then the vetex radius and conic constant can be calculated by the data. The error analysis shows that the accuracy are 0.053 mm and 9.610-5 for the vertex radius and conic constant, respectively. |
