	Study on time registration method for photoelectric theodolite data fusion (EI CONFERENCE) 会议论文 OAI收割 10th World Congress on Intelligent Control and Automation, WCICA 2012, July 6, 2012 - July 8, 2012, Beijing, China Yang H.-T.; Gao H.-B. 收藏 \| 浏览/下载：18/0 \| 提交时间：2013/03/25 In range measurement theodolite and radar constitute a real-time tracking system at different sites to track the same target in the air and get useful information exactly and timely. As the optical theodolite and radar have different sampling frequency and measurement system the data is sent to the fusion center is asynchronous. This paper proposed a time registration method based on multi-sensor data using Wavelet neural network algorithm which not only better solved the basic problems of theodolite fusion tracking but also improve the efficiency of data fusion. Simulation experiment and comparison with other time registration method have shown the advantage of this method. 2012 IEEE.

	The study on the temperature influence of the grain near infrared spectrum analysis (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Information Processing, August 21, 2005 - August 26, 2005, Changchun, China 作者: Zhang J.; Chen X.; Chen X. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 Near-infrared spectroscopy was used to examine unmodified wheat powder at temperatures of 14-65C. A self-regulating diffuse reflected assembly was used to permit collection of spectra of powder samples. Changes to the shape and peak location of the 1400-1500nm and 1900-1950nm water absorption bands 2000-2050 2070-2110 and 2250-2300nm bands were measured as temperature varied. Results indicated that temperature changes resulted in slight changes to the water absorption bands in 1400-1500nm and 1900-1950nm regions. From 14-65C the 1400-1500nm and 2050-2150nm band shifted approximately 10nm and 16nm toward shorter wavelengths and 2000-2050nm band shifted approximately 14nm toward longer wavelengths. In addition few numbers of samples cannot constitute good temperature insensitive calibration model even though the spectra were obtained at wide temperature condition.
	Optoelectronic non-contact measuring method for the taper of a bore (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China 作者: Zhang G.; Zhang G.; Zhang G.; Yang L.; Yang L. 收藏 \| 浏览/下载：36/0 \| 提交时间：2013/03/25 Based on laser optical triangulation displacement and grating displacement inspecting principle optoelectronic non-contact inspecting method and inspecting system for the taper of small-calibre bore are presented. In this paper the constitute and overall structure of the system are described. Then the taper inspecting method and principle of the bore are discussed and theoretically analyzed and also the corresponding mathematics model is established. As inner diameter measurement is an important parameter for the taper of small-bore an inner diameter laser non-contact measuring method is presented based on the structure characteristic of the taper of small-calibre bore which adopted optoelectronic probe sensitive device (PSD) and laser optical triangulation inspecting principle. And then the laser probe inner diameter measuring system is designed based them. Moreover the measuring principle the project of optical system of this measuring system are illuminated in detail in this article. The accuracy of inspecting system is verified by experiment. The results showed that the measuring error of inspecting system is superior to 0.005 and the inspecting repetition is superior to 0.003. It indicates that the system can fulfill the inspecting accuracy demand for inspecting the taper of the small-calibre bore and the inspecting method is applicable.
