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.

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.
