	Alignment of off-axis asphere and compensator with four poles (EI CONFERENCE) 会议论文 OAI收割 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, November 19, 2008 - November 21, 2008, Chengdu, China 作者: Li J.; Chen Y.; Li J.; Li J.; Wang P. 收藏 \| 浏览/下载：59/0 \| 提交时间：2013/03/25 Aspheres are utilized widely thanks to the development of optical design manufacture and testing. Compensators are usually necessary when aspheres are under test. The alignment of aspheres and their compensators is a risk because it's tough to check whether the compensators work in right way. A new method of alignment with four poles is put forward in this paper. Optical interval error can be tight while it is quite important due to direct influence on central curvature conic constant and high order coefficients of aspherical surface. A modified on-axis Foucault apparatus is set up since it makes the optical axis visible and helps to control the error of off-axis amount. Some small holes are drilled in the metallic cell of the compensator so that the ends of poles can be stably relied on in order to increase operational repeatability. The method has been carried out practically and it matches the measurement result given by a set of theodolites. 2009 SPIE.
	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：17/0 \| 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.
	Photonic micro and sub-micro structures in LiNbO3 crystals (EI CONFERENCE) 会议论文 OAI收割 ICO20: Materials and Nanostructures, August 21, 2005 - August 26, 2005, Changchun, China 作者: Wang P. 收藏 \| 浏览/下载：20/0 \| 提交时间：2013/03/25 High energy lasers processing of materials is knowing an increasing interest since it not only can make manufacturing faster cleaner and more accurate but also because it opens up entirely new technologies and manufacturing methods that are simply not available by using standard techniques. In this paper an experimental set-up based on pulsed KrF excimer Laser assembled for surface patterning of mono and two-dimensional (1D-2D) micro and submicro structures on LiNbO3(LN) crystal will be described in detail. The apparatus has been used to produce photonic structures in LN both by patterning of PMMA photoresist and by direct surface patterning through laser ablation or direct laser writing. The structures and properties of the photonic crystals fabricated by using this apparatus have been investigated and the preliminary results will be presented.
