	Analysis of a diffractive microlens using the finite-difference time-domain method (EI CONFERENCE) 会议论文 OAI收割作者: Liu Y.; Liu H.; Liu H.; Liu H.; Liu Y. 收藏 \| 浏览/下载：21/0 \| 提交时间：2013/03/25 The finite-difference time-domain (FDTD) method is used as rigorous electromagnetic analysis model to calculate the field for a diffractive microlens (DML). The FDTD is used for the entire solution rather than using a near- to far-field propagation method to obtain the far-field energy distribution thus all the results are vector based. We derived a formula to calculate the magnitude of electric field which is time dependent and can be used to graphically show the light wave propagation and focusing process through a DML. Both the comparison and the integral methods are presented to obtain wave amplitude in full solution space and the distribution of light energy behind a DML is illustrated based on the wave amplitude. The formula of diffractive efficiency of the DML is derived from a time-averaged Ponyting vector which can indicate the propagation direction of light energy. Application of these formulations in the analysis of a DML example demonstrates the high accuracy and efficiency of our method. 2010 Society of Photo-Optical Instrumentation Engineers.
	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：19/0 \| 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.
