	Phase-laser ranging system based on digital signal processing for optoelectronics theodolite application (EI CONFERENCE) 会议论文 OAI收割 2010 3rd International Conference on Advanced Computer Theory and Engineering, ICACTE 2010, August 20, 2010 - August 22, 2010, Chengdu, China 作者: Liu Y.-S. 收藏 \| 浏览/下载：40/0 \| 提交时间：2013/03/25 In order to meet requirement of high accurate ranging the laser ranging system is designed for optoelectronics theodolite application by this paper based on digital signal processing. Variable modulating method is used to solve the antinomy between the measuring range and accuracy. Frequency mixing is adopted to reduce the frequency of the signal which can lower the requirement for hardware. The high ranging accuracy is achieved by way of Fast Fourior Transform (FFT) using digital signal processor and error correcting factor. Experiment results indicate that using digital signal processing method can reduce the influence of surroundings and hardware system and obtain high ranging accuracy. 2010 IEEE.
	Dynamic evaluation system for interpolation errors in the encoder of high precision (EI CONFERENCE) 会议论文 OAI收割 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, November 19, 2008 - November 21, 2008, Chengdu, China 作者: Liang L.-H.; Sun Y.; Sun Y.; Wan Q.-H. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 In order to measure dynamic interpolation errors of photoelectric encoder of high precision the dynamic evaluation system of interpolation errors is introduced. Firstly the fine Moire signal of encoder which is collected with the high-speed data gathering card into the computer is treated to equiangular data with the method of linear interpolation. Then the analysis of harmonic wave with the FFT is processed. Compared with the standard signal the dynamic interpolation errors of the encoder are calculated. Experimental results show that the precision of the dynamic evaluation system of interpolation errors is 0.1 %( pitch). The evaluation system is simple fast high precision and can be used in the working field of the encoder. 2009 SPIE.
