Mn2+ may occupy Ca2 site (Mn2+(I)) to generate a yellow emission band at 574 nm or Sc3 site (Mn2+(II)) with red emission band at 680 nm. Efficient energy transfers from the green emitting Ce3+ to both Mn2+(I) and Mn2+(II) occur upon blue excitation into Ce3+. Concentration dependence of Mn2+ emission is analyzed based on Ce3+-Mn2+ energy transfer  steady state rate equations  and fluorescence lifetimes. Energy transfer efficiency (nT) and rate (W) are calculated with values as high as 45% and 14.01106 s-1  respectively. 2011 Elsevier B.V.   Design of astromesh deployable concentrator used in space concentrating photovoltaic system 会议论文  OAI收割 2012 作者:  Zhang P.;  Zhang Y. 收藏  |  浏览/下载：8/0  |  提交时间：2013/03/28 High beam quality all-solid-state 1053nm nd: Glass amplifier shaping by LCSLM at repetition frequency (EI CONFERENCE) 会议论文  OAI收割 2nd International Conference on Optical, Electronic Materials and Applications 2012, OEMA 2012, May 25, 2012 - May 26, 2012, Chongqing, China 作者:  Zhang X.;  Qiu J.;  Zhang X.;  Zhang X. 收藏  |  浏览/下载：72/0  |  提交时间：2013/03/25 A laser amplifier of LD pumping Nd: glass with a high beam quality and stability  the modulation degree near field is less than 1.23:1.

First of all  this paper recommended the Splicing structure of CCD in the APRC Based on this  auto-focus method which is made use of the overlapping area of CCD mosaic structure was proposed  combined with the characteristic of the imaging mode. After analyzing of experiments about all kinds of focus-examine functions based on image processing  the gradient square function has been chosen. The experimental results show that the proposed auto-focus method for the APRC is proved to be feasible and real-time. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).   Detection Capability Analysis of Lunar Retroreflector 会议论文  OAI收割 2011 作者:  Zhao Y.;  Yu J.;  Zhao Y.;  Zhao Y. 收藏  |  浏览/下载：3/0  |  提交时间：2013/03/28 Correction of the non-uniformity for multi-TDICCD mosaic camera on FPGA (EI CONFERENCE) 会议论文  OAI收割 2010 International Conference on E-Product E-Service and E-Entertainment, ICEEE2010, November 7, 2010 - November 9, 2010, Henan, China Zhu H.; Xue X.; Ma T.; Li H.; Si G.; Guo Y. 收藏  |  浏览/下载：21/0  |  提交时间：2013/03/25 To solve the non-uniformity problem of multi Time Delay Integral Charge Couple Device (TDICCD) mosaic camera  several common non-uniformity correction methods are discussed. Secondly  a non-uniformity correction algorithm is proposed and implemented on Field-Programmable Gate Array (FPGA) platform. Firstly  the correction algorithm is designed. Finally  the generation and definition of non-uniformity are introduced  considering the fix-point processing ability of FPGA  the correction algorithm is optimized properly  and implemented on FPGA. The experimental results indicate that the non-uniformity can be decreased from 8.3%to 2.0% in 1s for 3-TDICCD mosaic camera's images with the proposed correction algorithm at 96TDI stage  proving that this correction algorithm is of high real-time performance  good practicality and satisfies the requirements of the target system. 2010 IEEE.
