	Design of transmission of high-speed CCD driving signals (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China 作者: Zhang S. 收藏 \| 浏览/下载：70/0 \| 提交时间：2013/03/25 In order to overcome the distortion problem of CCD driving signals caused by signal transmission the detail implementation of transmission of high-speed CCD driving signals based on transmission line theory is discussed. The CCD driving signals are critical to the CCD to produce high quality images. In high speed application these drivers will occupy more circuit board areas and can not be put very close to the CCD. So the driving signals must be transmitted. Because the CCD exhibits capacitive load the driving signals distortion problem is much severe. Transmission line theory is used to analyze the problem. The method of source termination is adopted to avoid signal reflections. Meanwhile the characteristic impedance of the circuit board and the resistance of terminal resistor are designed small enough to decrease the rising and falling time of the driving signals. Experimental results show that there is no distortion of the high speed driving signals after transmission. 2011 IEEE.
	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：26/0 \| 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.
	The application of auto-controlled liquid crystal light valve arrays to photolithography shutter (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China 作者: Chen Y. 收藏 \| 浏览/下载：14/0 \| 提交时间：2013/03/25 Photolithography shutter is usually used to control exposure in order to obtain patterns of code disc and metrology grating which are the core components of optical shaft encoder. But perforated film as photolithography shutter has many disadvantages such as taking too long time to perforate easily making wrong code lower reusable ratio. Mathematical models for resist property luminous efficiency and exposure have been established by deducing their relations for avoiding the disadvantages which provides the theory of using liquid crystal light valve (LCLV) replacing proforated film. Based on operating principles of LCLV and control theories of photolithography shutter the principle diagram of control circuit of LCLV arrays has been designed according to theirs control principles. In the control system LCLV arrays as photolithography shutter are realized by adopting DS75451 to drive them and using AT89C51 chip to control them. By photolithographic experiment the patterns of code disc are good the edges of lines are vertical it indicates LCLV arrays as photolithography shutter may control exposure and light passing accords with the intending requires. It proves using LCLV arrays replacing perforated film as photolithography shutter is feasible completely.
