Because of laser's harsh electromagnetic environment  LCD module coupled to the electromagnetic interference easily  leading to not work normally. This paper analyzed the interference coupling mechanism. On the basis of the analysis results  LCD module's field-line coupling is calculated by Taylor form's BLT equation. The calculation result is verified by experiment. The results show that  due to the field-line coupling  the data line of LCD module existed interference voltage  interference voltage value is 1V. The interference voltage is larger than the LCD module's noise margin. LCD module must shield the interference. 2012 IEEE.   A design study on the CSNS LEBT pre-chopper 期刊论文  OAI收割 Science China Press, 2010, 页码: 5 作者:  Li CH(李春华);  欧阳华甫;  Peng J(彭军);  LIU HuaChang;  OUYANG HuaFu 收藏  |  浏览/下载：39/0  |  提交时间：2015/12/14 pre-chopper  rise/fall time  electromagnetic shield   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.
