	A design on a control method of a new type of focal plane shutter (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 Xue L.; Ming L.; Zheng L.-N.; Zhou J.-F.; Zhang H.-W.; Zhang J.-C. 收藏 \| 浏览/下载：33/0 \| 提交时间：2013/03/25 In order to ensure appropriate exposure time and no exposure while electric charge is transferring after taking a photograph it is necessary to have the shutter mechanism cooperate with CCD for area CCD aerial cameras. 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.
	In situ long trace profiler for measurement of Wolter type-I mirror (EI CONFERENCE) 会议论文 OAI收割 Advances in Metrology for X-Ray and EUV Optics III, August 1, 2010 - August 2, 2010, San Diego, CA, United states 作者: Chen B.; Chen B. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 The surface profile of Wolter type-I mirror has a great impact on the performance of Solar X-ray Telescope. According to the existing fabrication instrument and experimental conditions in our lab an in situ Long Trace Profiler is developed and set up on the fabrication instrument in order to measure the surface profile of Wolter mirror in real time during fabrication process. Its working mechanism structural parameters and data processing algorithm are investigated. The prototype calibrated by a standard plane mirror is used to measure a sample of Wolter type-I mirror. The results show that our prototype can achieve an accuracy of 2.6rad rms for slope error with a stability of 1.33rad during the whole measurement period. This can meet further fabrication requirements. 2010 Copyright SPIE - The International Society for Optical Engineering.
	The effect of N/Si ratio on the a-SiiH/SiNx interface of a-SirH/SiNx TFT (EI CONFERENCE) 会议论文 OAI收割 Asia Display 2007, AD'07, March 12, 2007 - March 16, 2007, Shanghai, China Liu J. e.; Gao W.; Liao Y.; Jing H.; Fu G. 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 The threshold voltage of a-Si: H/SiNx TFT will shift under long time gate bias stress it is mostly leaded by charge trapping in gate insulator and defect creation in semiconductor. And it is hard to be applied in AMOLED for TFT because of its threshold voltage shift. In allusion to the phenomenon of charge trapping a series of SiNx insulating films in different N/Si(0. 87 -1.68) ratio were deposited by PECVD in this paper controlling different flow ratio of source gas SiH4 and NH3 and a great deal of tests (ellipsometer infrared absorption (FTIR) and Electron Dispersion Spectrum (EDS) test ) were done on these samples. Based on these SiNx insulators three different capacitance samples in MIS structure were done degraded experiments and C-V tests on these samples were done. The C-V curve shift of capacitance which contained SiNx with slightly N-rich(N/Si is bigger slightly than 1. 33) was not evident before and after degradation this result indicated that the defect density of this type SiN x was smaller and could restrain charge chapping in the interface of a-Si:H/SiNx effectively. So that as gate insulator of TFT SiN x with slightly N-rich could decrease the threshold voltage shift of TFT and enhance its stability effectively.
