We design the cold light source in the measurement of near infrared spectroscopy. Cold light source consists of high-power op amp OPA549 high current constant current source and proportion integral differential (PID) control algorithm. As is shown in the experimental results  the method is better  the overshoot is very small  the stability is excellent in the process of soft-start. While light intensity was able to meet the requirements of near-infrared instruments to measure. 2011 IEEE.   Development and radiance calibration of three-waveband camera (EI CONFERENCE) 会议论文 International Symposium on Photonics and Optoelectronics, SOPO 2010, June 19, 2010 - June 21, 2010, Chengdu, China Lu Z.; Sun Q.; Wang J.; Lu Z.; Liu Y. 收藏  |  浏览/下载：23/0  |  提交时间：2013/03/25 An imaging system with three-waveband sharing one lens and an area CCD was developed. By rotating different filters into the beam path  the required waveband was selected. The optical system which can image in ultraviolet  visible and near infrared region was designed and the signal collecting system was integrated. The optical design and system integration have some advantages such as low cost  small size and light in weight. To obtain a high imaging quality  the radiation calibration is carried out in order to establish the relation between the average grey level of output image and the input radiance from the integrating sphere. According to the calibration data in experiments  the radiation dynamic range and the best working point of the system are determined. The experiment result shows that the dynamic range of the image system is maximal when the exposure time is 8ms in ultraviolet  0.5ms in visible and 0.125ms in near infrared region. 2010 IEEE.   Development of a new diffuse near infrared food measuring (EI CONFERENCE) 会议论文 Sitxh International Symposium on Instrumentation and Control Technology: Signal Analysis, Measurement Theory, Photo-Electronic Technology, and Artificial Intelligence, October 13, 2006 - October 15, 2006, Beijing, China Zhang J.; Piao R. 收藏  |  浏览/下载：24/0  |  提交时间：2013/03/25 Industries from agriculture to petrochemistry have found near infrared (NIR) spectroscopic analysis useful for quality control and quantitative analysis of materials and products. The general chemical  polymer chemistry  petrochemistry  agriculture  food and textile industries are currently using NIR spectroscopic methods for analysis. In this study  we developed a new sort NIR instrument for food measuring. The instrument consists of a light source  12 filters to the prismatic part. The special part is that we use a mirror to get two beams of light. And two PbS detectors were used. One detector collected the radiation of one light beam directly and the value was set as the standard instead the standard white surface. Another light beam irradiate the sample surface  and the diffuse light was collected by another detector. The value of the two detectors was compared and the absorbency was computed. We tested the performance of the NIR instrument in determining the protein and fat content of milk powder. The calibration showed the accuracy of the instrument in practice.
