In order to break through the limitations of traditional optical imaging systems on spectral sensitivity, spectral resolution and spatial resolution of spectral imaging technology, the subject is led by the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Shanghai Institute of Technical Physics, Chinese Academy of Sciences, and Beijing Normal University. For many units, the passive optical hyperspectral intensity correlation imaging technology was first proposed in the world. After three years of technological breakthrough, it has broken through the optimization design of a random phase encoder, the design of a random dispersion spectroscopic light path, and an efficient and fast 3D multispectral image reconstruction algorithm. With key technologies, we successfully developed a single-exposure high-intensity intensity correlation imaging outfield test prototype with original independent intellectual property rights, and completed a typical application scenario imaging experiment based on an aerial platform, fully demonstrating the new spectrum imaging solution. High-speed, high-efficiency acquisition of spectrally resolved image information.

The research group is also based on the single photon detection sensitivity intensity-correlation spectral imaging technique, the application of optical parametric noiseless image amplification technology in the detection of high-sensitivity intensity associated remote sensing imaging, quantitative description of the image acquisition capability of the intensity-related imaging system, system optimization design, and images. A series of world-class theoretical and experimental results have been obtained in the reconstruction and construction of the performance evaluation index system for the optical intensity related imaging system.

The single-exposure hyperspectral intensity correlation imaging technique has the advantages of high detection sensitivity, high image information acquisition efficiency, and high spectral and spatial resolution. In the areas of resource environment and disaster assessment, this technology can make up for the insufficiency of existing spectral remote sensing imaging technology. It can obtain hyperspectral remote sensing images under weak light sources and other adverse weather conditions, and better meet the needs of many remote sensing applications such as urban security, land resources monitoring, natural disasters, forestry, agriculture, water conservancy, and the environment.
