The first domestic commercial laboratory spectral radiance chromaticity calibration system passed the acceptance test
[ China Instrument Network Instrument Development ] On the morning of November 16, the project of "Visible Light-Short Wave Infrared Spectroscopy Radiation Chroma Calibration System" undertaken by the Optical Remote Sensing Center of Anhui Institute of Optics and Mechanics of the Chinese Academy of Sciences was organized by Changguang Satellite Technology Co., Ltd. in Changchun, Jilin. Project acceptance review. The system is primarily used for laboratory spectral/radiation/chroma calibration of visible, short-wave infrared infrared, aerospace and terrestrial optoelectronic imaging/detection equipment.
Spectral calibration system
The review team composed of experts from relevant departments of Changguang Satellite Technology Co., Ltd. listened to the project development summary and system trial operation report, reviewed the relevant materials, and agreed to pass the project acceptance after questioning and discussion.
Changguang Satellite Technology Co., Ltd. is the first commercial remote sensing satellite company in China, dedicated to satellite, UAV development and remote sensing information services. During the development of the calibration system, the project team has overcome the key techniques such as 6-order color temperature adjustment of large-caliber integrating sphere radiation source, large dynamic range radiation standard transmission, and system-level spectral chromaticity calibration. Spectral radiance, uniformity, and dynamics. The core technical indicators such as scope have reached the international advanced level.
The successful development of the system provides a complete physical response model for the optical remote sensor, which provides technical support for the calibration of the full-life spectral radiance chromaticity calibration, and provides technical support for improving the quantitative information level of remote sensing data products.
