Numerical simulation results show that for given device structure with wavelength of 1.55 m  the feedback coupling coefficient and the surface radiation coupling coefficient of the second-order grating have great influence on the emission characteristics of the device. By choosing different duty cycles of the grating  we can change the two coupling coefficients  which affect the emission characteristics. For an overall consideration  an optimal duty cycle of 0.43 is chosen. The optimized results show that the device works without degeneracy modes and spatial burning hole. Besides  the side-mode suppress ratio (SMSR) and external differential quantum efficiency reach as high as 42 dB and 47%  respectively. 2010 SPIE.   Electromagnetic radiation test of power driver module in optical tracking system and electromagnetic compatibility (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者:  Yu H. 收藏  |  浏览/下载：34/0  |  提交时间：2013/03/25 In order to solve the conductive ring module's interference problems  measured the electromagnetic radiation of Power drive module  and used test results analysis the electromagnetic compatibility of the conductive ring  identified and implemented appropriate EMC (electromagnetic compatibility) measures. When optical tracking system working  test equipment can not be fixed. Therefore  from the electromagnetic radiation theory  the paper analyzed the electromagnetic radiation of the power drive module. From it  determine the EMC pre-compliance test method for electromagnetic radiation of power drive module. Based on Test results  calculate the interference voltage of wire in Conductive ring  and then determine the corresponding EMC method. The results show that  when The power drive module Radiate Electromagnetic waves  wires would coupled common mode interference voltage  its frequency is 3MHz  amplitude is about 10V  it would interfered the operation of sensor. By reducing the area of ground loops  used shielded cables  final rule out the interference. 2010 IEEE.   Bootstrap loader design of aerospace payload controller based on TSC695F (EI CONFERENCE) 会议论文  OAI收割 2010 2nd International Conference on Computational Intelligence and Natural Computing, CINC 2010, September 13, 2010 - September 14, 2010, Wuhan, China Xu W.; Piao Y. 收藏  |  浏览/下载：37/0  |  提交时间：2013/03/25 Anti-radiation TSC695F is usually used as aerospace payload controller in tasks to ensure the aerospace payload having extremely high reliability in abominable space environment. The processor bases on SP ARC V7 architecture with parity check and EDAC  so it could design out high reliable bootstrap loader to guarantee the operation system of VxWorks and application codes loaded correctly and worked stable and high effective. First  this paper put forward the system hardware composition and boot mode which apply for aerospace payload  then it makes clear the related contents of register group initialization  stack initialization  system hardware initialization in bootstrap loader of TSC695F and give out the method to establish TRAP table. That's all through comparing different type of organize mode of program image. After that  compiling of target codes have been described and the kernel code of MakeFile had been given at the same time for reference aimed at the realization of engineering. Although this paper is based on TSC695F  but it could be extended to other embedded system based on SP ARC for bootstrap loader analysis and design  for example  the TSC697 which based on SP ARC V8 with higher performance  so this paper has extremely high engineering value. 2010 IEEE.   首页 上一页 1 2 下一页 末页
