The composite encoder can achieve the angle measurement as the absolute encoder  and the servocontrol as the increment encoder. Base on the requirement of the Measurement and Control Equipment  the Composite code disc and the slot is designed  then the precision test is implemented on the composite optical encoder. The experimental result shows that the composite optical encoder not only output the measurement of the angle  but also provides speed feedback control signal. It has advantages of small volume  light weight  which can meet the requirements of Measurement and Control Equipment. 2009 IEEE.   Study of microsphere plate photomultiplier tube (EI CONFERENCE) 会议论文  OAI收割 ICO20: Remote Sensing and Infrared Devices and Systems, August 21, 2005 - August 26, 2005, Changchun, China 作者:  Wang X.;  Li Y.;  Li Y.;  Li Y.;  Li Y. 收藏  |  浏览/下载：32/0  |  提交时间：2013/03/25 The photomultiplier tube (PMT) that can work in different wavelength is an important detector device in remote sense technology. Microsphere plate using glass beads 50to 70m in diameter sintered together is the core component of the microsphere plate photomultiplier tube It is a novel two-dimension electron multiplier. The electrons gain for a single plate is about 1017 and do not have the phenomenon of ion-feedback. Furthermore the fabrication process is very easy. In this paper  much interest was put on the microsphere plate photomultiplier tube. Based on the analyses from the theory and the experiment result  we point out the key technology for fabricating PMT is how to obtain glass beads with narrow range in diameter and how to sinter the glass beads with a sufficient pylome. Factors affect the gradating technology and sintering process along with the solution to them is presented. In the last  the structure scheme and technological characteristic for fabricating microsphere plate photomultiplier tube were given. The pulse rising-time of MSP-PMT is below 400ps suitable to the detection of high-speed pulse. As easy to be fabricated and has great advantage over MCP multiplier in the ratio of performance to price  the microsphere plate photomultiplier tube is a promising dim-light detector.   Progress in molecular mechanisms of circadian rhythm in Drosophila 期刊论文  OAI收割 PROGRESS IN BIOCHEMISTRY AND BIOPHYSICS, 2005, 卷号: 32, 期号: 1, 页码: 3-8 作者:  Guo, AK 收藏  |  浏览/下载：27/0  |  提交时间：2012/07/23 Drosophila  entrainment  circadian rhythm  circadian clock  clock gene  feedback loop  CLOCK  GENE  MELANOGASTER  LIGHT  PHOTORECEPTOR  CRYPTOCHROME  MUTATION  NEURONS  MUTANT  FLIES   Single steady frequency and narrow line width external cavity semiconductor laser 会议论文  OAI收割 conference on advanced characterization techniques for optics semiconductors and nanotechnologies, san diego, ca, aug 03-05, 2003 Zhao WR; Jiang PF; Xie FZ 收藏  |  浏览/下载：21/1  |  提交时间：2010/10/29 external cavity semiconductor laser  light feedback  single longitudinal mode  spectral line width  FEEDBACK  DIODE
