The ground object illumination has a wide range which is from 4000Lx to 100000Lx  so a shutter which is high efficient and a continuous stepless adjustment are also required. This paper introduces the fundamental principle  structural design and control procedure about this new focal plane shutter. Under the control of DSP  the velocity of shutter curtain governed by the shutter motor can be not only precisely controlled  but also the durability and the reliability are increased. The experiment results have shown that this new shutter has the higher stability of movement  long life span with more than 105 operating times  a wide range of exposure time from1/ 50s to 1/ 320s(depending on the slit width)and the exposure error is less than 10%. With the CCD gain adjustment  the performance of this shutter is fully satisfied with the requirements of area CCD aerial cameras. 2010 IEEE.   Optically trapped quasi-two-dimensional Bose gases in a random environment: Quantum fluctuations and superfluid density 期刊论文  OAI收割 Physical Review A, 2010, 卷号: 82, 期号: 4 K.

Within small space occupied  it can obtain real images with various resolutions. Moreover  using plate traveling-wave Ultrasonic Motor as its driven motor can reduce energy loss  improve control precision and ensure image obtaining being real-time and stable. Disc varifocal mechanism driven by plate traveling-wave Ultrasonic Motor is high-response  and variation in load doesn't affect its performance parameter. Therefore  applying disc varifocal mechanism in scene matching navigation system  combing software and hardware  can obviously improve the accuracy  real-time and robust of scene matching navigation system. The experiment showed that when the weight of mechanism was 1.5kg  the shortest starting was 0.6ms  and the shortest shutoff was 0.5ms. 2009 IEEE.   Structural change of laser-irradiated Ge2Sb2Te5 films studied by electrical property measurement 期刊论文  OAI收割 j. non-cryst. solids, 2008, 卷号: 354, 期号: 52-54, 页码: 5563, 5566 Huajun Sun; Lisong Hou; Yiqun Wu; Jingsong Wei 收藏  |  浏览/下载：1232/266  |  提交时间：2009/09/22 Amorphous metals  metallic glasses  Alloys  Amorphous semiconductors  III-V Semiconductors  Crystallization  Glass ceramics  Conductivity  Films and coatings  Sputtering  Glass transition  Radiation effects  Laser-matter interactions  Microcrystallinity  Phases and equilibria  Structure  Long range order  Short-range order  Structural relaxation  X-ray diffraction   Quantum phase transitions and Bose-Einstein condensation of magnons in hexagonal spin systems 期刊论文  OAI收割 JOURNAL OF PHYSICS-CONDENSED MATTER, 2007, 卷号: 19, 期号: 38 Wang, HT; Wang, Y 收藏  |  浏览/下载：26/0  |  提交时间：2013/09/24 MEAN-FIELD THEORY  LONG-RANGE ORDER  MAGNETIC-FIELD  LADDER CU-2(C5H12N2)(2)CL-4  HEISENBERG-ANTIFERROMAGNET  CRITICAL-POINT  HALDANE GAP  STATE  TLCUCL3  RBFECL3   Preliminary investigation on solid solution softening effects on NiAl based alloys induced by minor Ru alloying addition 期刊论文  OAI收割 Materials Science and Technology, 2007, 卷号: 23, 期号: 2, 页码: 189-194 H.
