	Design of driving circuit for binocular CCD image system (EI CONFERENCE) 会议论文 OAI收割 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optoelectronic Materials and Devices for Detector, Imager, Display, and Energy Conversion Technology, April 26, 2010 - April 29, 2010, Dalian, China 作者: Zhang X.; Zhang X.; Zhang X. 收藏 \| 浏览/下载：42/0 \| 提交时间：2013/03/25 The paper designs a driving circuit of high sensitive wide dynamic and high signal-to-noise ratio for binocular CCD imaging system which adopts a Dalsa-made high resolution full-frame 33-mega pixels area CCD FTF5066M. Inner structure and driving timing of the FTF5066M sensor are presented. Field Programmable Gate Array (FPGA) is used as the main device to accomplish the timing design of the circuits and power driver control of the two sensors. By using the Correlated Double Sampling (CDS) technique the video noise is reduced and the SNR of the system is increased. A 12- bit A/D converter is used to improve the image quality. The output rate of the imaging system designed with integrated chip can reach to 1.3 frames per second through bi-channel. For its good performance low power consumption and small volume the driving system can be applied to aeronautics and astronautics field. With a further improvement a maximum data output rate of 2.7 frames per second can be reached through all the eight channels of the two CCDs. 2010 Copyright SPIE - The International Society for Optical Engineering.
	An 8-channel, area-efficient, low-power audio sampling rate converter (EI CONFERENCE) 会议论文 OAI收割 9th International Conference on Electronic Measurement and Instruments, ICEMI 2009, August 16, 2009 - August 19, 2009, Beijing, China 作者: Liu Y.; Liu Y.; Liu Y.; Wang D. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 A novel 8-channle third area-efficient next a new Timing Division Multiplexer (TMD) scheme lowers clock working rate to minimum in order to save power a novel memory addressing scheme reduces 20% data memory at least. Experiments show proposed methods could not only saved hardware resources but also reduce power consumption low-power audio sampling rate converter is proposed in this paper so it is very suitable for consumer electronics. 2009 IEEE. conversion ratio is 2:1 and 4:1. Filter design and implementation are the key points for the converter. First excluded data and coefficients memories adopting multiplier-free Arithmetic Unit (AU) and rounding methods allows its realization in a cell area of only 0.038mm 2 in 0.18 m technology
	Angular rate of test table based on high-speed non-contact measurement (EI CONFERENCE) 会议论文 OAI收割 9th International Conference on Electronic Measurement and Instruments, ICEMI 2009, August 16, 2009 - August 19, 2009, Beijing, China 作者: Yang L.; Zhao Y.; Zhao Y.; Zhao Y.; Yang L. 收藏 \| 浏览/下载：140/0 \| 提交时间：2013/03/25 This article will introduces a high-speed non-contact method that can measures the angular rate of a test table though an objective perspective. This method adopts a collimator tube that can be measured as a target fixed to the test table and the target corresponds to the angular position of the test table. In the process of the table rotating the camera will to keep track of the objective at a high speed. Due to the high sampling frequency of the high-speed camera instantaneous angular rate of test table can be measured. With pixel subdivision technology its measuring accuracy can be up to 0.02 pixels. We use this methods measured a low-speed test table's angular rate and analyzed the data. The error analysis shows when the rate of the test table is 0.20/s the accuracy of the method can achieve 0.0220%. 2009 IEEE.
