| 中文摘要: | A quantitative method in the fine grinding stage on the base of self-made test system is presented and is investigated by the experiments is presented in the paper. The contact mechanical equipment measures aspheric vector heights directly by a long rail and high precision grating probe. After calibrating system error and preprocessing data, the surface shape error and wave-front aberration coefficients of aspheric mirror are obtained by Zernike polynomials wave-front fitting the collected discrete three-dimensional data. Comparison with Hartmann sensor test method through polishing the aspheric mirror, the accuracy of wave-front error is in approximate agreement with each other, and the accuracy can meet the requirement of larger aperture aspheric mirror in the fine grinding stage. By experiment investigation in the process of manufacture and test, the system can guide machining in the fine grinding stage. The measurement system shows the advantages of low costs, operating convenience, as well as high-speed calculation. |
