Changguang Institute's video hyperspectral camera has successfully developed domestic hyperspectral remote sensing

[ Instrument Network Instrument Development ] The Light Conference 2019 International Conference ended successfully at the Changchun Institute of Optics and Mechanics. In the invited expert report of the conference, the researcher of Changchun Institute of Optics and Mechanics Hu Changhong made "pixel-level tunable video hyperspectral intelligent imaging technology". "Aroused widespread concern. In April 2019, the Hanchengshan project team of Changchun Institute of Optics and Light and the Wang Xiaoyi project team collaborated to develop a prototype of video hyperspectral camera based on pixel-level spectroscopic technology with completely independent intellectual property rights. The results can be used for civil disaster reduction, land resources, precision agriculture. / Forestry, food and drug testing, industrial testing (product defects), cultural relics identification and other fields.

Video hyperspectral camera prototype

The project relies on the research of video hyperspectral imaging technology in Jilin Province's scientific and technological research project. According to project leader Hu Changhong, the camera is a gaze-type hyperspectral camera with light weight, small size, simple structure and high stability. High-frame-rate gaze imaging and single-exposure high-spectral imaging with multiple spectral data, and high spatial resolution, high temporal resolution, and high signal-to-noise ratio hyperspectral, without the need for data calculations Video imaging capabilities.

At present, China's hyperspectral imaging technology is usually based on prism/grating spectroscopic, interference or linear gradient filters and other spectroscopic systems. It uses push-sweep or sweep-sweep mode to achieve high-spectral video-level imaging. Video hyperspectral imaging technology based on pixel-level spectroscopic technology has been mastered by a few foreign companies such as IMEC in Europe, Silios in France, and Pixelteq in the United States. There are few reports of similar products in China. The Hanchengshan project team and the Wang Xiaoyi project team of Changchun Institute of Optics and Fine Mechanics have successfully solved the technical problems of high-spectrum pixel-level spectroscopy, pixel-level optomechanical integration, high-frequency high-speed electronics design and spectral data inversion recovery. Video hyperspectral imager based on pixel-level spectroscopic technology. Compared with similar foreign products, the performance of the index is quite high, successfully breaking the monopoly of similar foreign technology and enriching the imaging methods in the field of hyperspectral remote sensing in China.

At present, the project team used the results to perform imaging recognition experiments on camouflage and plants, and the results were good. Next, the product will enter the stage of achievement transformation.
