	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：22/0 \| 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.
	Field emission properties of ZnO nanowires (EI CONFERENCE) 会议论文 OAI收割 ICO20: Display Devices and Systems, August 21, 2005 - August 26, 2005, Changchun, China Meng X. Q.; Shen D. Z.; Zhang J. Y.; Zhao D. X.; Lu Y. M.; Zhang Z. Z.; Fan X. W. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 ZnO nanowires were obtained by using a simple vapor solid process. The length of the nanowires is about 1 m with diameters ranging from 40 nm to 150 nm. X-ray diffraction (XRD) pattern confirms the nanowires are wurtzite structure with c-axis preferred orientation. Photoluminescence (PL) measurement shows a strong UV emission and a weak visible emission. Field emission (FE) results proved the nanowires have low turn-on voltage and high field enhancement factor which indicates ZnO nanowire is a suitable candidate for field emission display.
	Method for the fabrication of isometric mesh on the concave of a spherical substrate (EI CONFERENCE) 会议论文 OAI收割 2nd International Symposium on Advanced Optical Manufacturing and Testing Technologies - Advanced Optical Manufacturing and Testing Technologies, November 2, 2005 - November 5, 2005, Xian, China 作者: Feng X.-G. 收藏 \| 浏览/下载：35/0 \| 提交时间：2013/03/25 Metallic mesh has been widely used in electromagnetic interference windows. While the duty ratio of curved mesh equals to planar mesh' the theory of planar mesh may be applied to curved mesh according to equivalent-circuit model. So the idea that latitude lines intersect latitude lines to form isometric mesh on the concave of a sphere is put forward and the method of fabricating the mesh by concentric optical scan is introduced. The movement parts of equipment consist of an erection turning a horizontal dividing and a pitching dividing spindle. Firstly a spherical substrate is fixed on the horizontal dividing spindle that has been set horizontally on the erect turning spindle the substrate revolves around the axis of the erect spindle the tube of object lens that is fixed on the pitching dividing spindle steps at pitching direction and a revolving circuit of the substrate corresponds to a step of the tube. Gradually a set of latitude lines is attained. Afterward the substrate makes a quarter turn around the horizontal spindle another orientation latitude lines are also gained. Thus the isometric mesh on the concave of a spherical substrate is gained. The process comprises surface cleaning coating photoresist laser direct writing development evaporated film dissolving photoresist and plating. The fabricated spherical mesh has a line width of 7 m and a period of 600m. Experiment shows that infrared transmission and electromagnetism shield efficiency of the metallic mesh are relatively consistent with theoretical value.
