In the near infrared spectroscopy
detector of Charge-coupled Device requires very high stability for light source. 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.

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.

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.
