	Mid-frequency surface error test with a Foucault apparatus (EI CONFERENCE) 会议论文 OAI收割 3rd International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, July 8, 2007 - July 12, 2007, Chengdu, China 作者: Li J.; Li J.; Xuan B.; Li J. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 Testing of mid-frequency surface error is of the first importance for fast optics especially for large aperture aspherics. Foucault test plays a dominant role for surface error inspection before the digital interferometer age but it seems to have faded out these days because no quantitative results turn out. However an interferometer with high resolution CCDs is either unavailable or unaccessible in the process of manufacture. As its advantages are realized and recognized for the second time Foucault test is going back to the stage again. A new theory of calculating the contrast of the shadow pattern of Foucault test is put forward in this paper and some modifications are discussed upon the analyses of the limitation of traditional Foucault apparatus. A paraboloidal mirror was fabricated and tested by the modified Foucault apparatus whose effect has been proved to be great. The methods of controlling mid-frequency error are described in the other paper at this conference- "Multi-mode combine manufacturing technology for large aperture aspheric mirrors"1.
