Piezoelectric angular acceleration sensor is used to measure angular acceleration directly  Adaptive FIR filter based on LMS algorithm is established on DSP  by which angular acceleration signal can be filtered and corrected errors adaptively  then angular acceleration signals can be measured adaptively. This method avoids measurement errors and calculation noise by computing angular acceleration indirectly  thus improving measurement precision and making measurement results better than traditional methods. The gotten angular acceleration can be sent to servo control mechanism as feed forward control signals to improve control effects of servo turntable significantly. 2011 IEEE.   Study on image real-time interpretation based on particle filter (EI CONFERENCE) 会议论文  OAI收割 2011 International Conference on Mechatronic Science, Electric Engineering and Computer, MEC 2011, August 19, 2011 - August 22, 2011, Jilin, China 作者:  Liu S.-J. 收藏  |  浏览/下载：39/0  |  提交时间：2013/03/25 In order to satisfy to the real-time requirement of image interpretation system in photoelectric measurement equipments  a kind of hardware acceleration system with MIMD distributed multi-processor architecture based on SOPC technology is designed. The particle filter algorithm is proposed to process image interpretation for state estimation problem of nonlinear and non-Gaussian system. This algorithm does not involve conventional linearization transform  and has approximated the posterior probability density by a set of discrete particles. Therefore the approximate optimum result is educed. It has a high accuracy and a rapid convergence. Experimental results show that the algorithm be adequate to real time  accuracy and robustness  meets the requirement of image interpretation and possesses practical significance for engineering applications. 2011 IEEE.   Design of image interpretation and data-processing system based on SOPC (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 Wang Z.-Q.; Liu Z.-R.; Xie M.-J. 收藏  |  浏览/下载：37/0  |  提交时间：2013/03/25 In order to follow the development of image interpretation and data-processing system in photoelectric measurement equipments  a kind of hardware acceleration system is designed where MIMD distributed multi-processor architecture is used with SOPC technology. System hardware is composed of FPGA  SDRAM  SRAM  FLASH  and PCI bridge chip. Four Nios II embedded processors are integrated in a single FPGA chip  and communicate with each other by sharing memory. Experimental results indicate that the system meets the requirements of data-processing system in photoelectric measurement equipments and possesses practical significance for engineering applications. 2010 IEEE.   加速度对激光双频干涉仪测量误差的影响 期刊论文  OAI收割 中国激光, 2007, 卷号: 34, 期号: 5, 页码: 694, 698 张志平; 程兆谷; 覃兆宇; 朱健强 收藏  |  浏览/下载：1418/221  |  提交时间：2009/09/24 测量  measurement  激光双频干涉仪  laser dual-frequency interferometer  加速度  acceleration  累积误差  cumulative error  多普勒频移  Doppler frequency shift   高能量激光尾场电子加速的相关研究 学位论文  OAI收割 作者:  刘佳琦   |  收藏  |  浏览/下载：55/0  |  提交时间：2018/12/26 激光尾场电子加速  Laser Wakefield Acceleration  级联加速  Cascaded Acceleration  毛细管放电等离子体通道  Capillary Discharge Waveguide  电子注入  Injection of Electron  电子束脉宽测量  Electron beam duration measurement
