First of all  this paper recommended the Splicing structure of CCD in the APRC Based on this  auto-focus method which is made use of the overlapping area of CCD mosaic structure was proposed  combined with the characteristic of the imaging mode. After analyzing of experiments about all kinds of focus-examine functions based on image processing  the gradient square function has been chosen. The experimental results show that the proposed auto-focus method for the APRC is proved to be feasible and real-time. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).   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.;  Chen X.;  Zhang J. 收藏  |  浏览/下载：23/0  |  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.
