图像、光谱、偏振态多维全光信息一体化获取技术研究

An innovative principle, scheme, and technique are proposed for integrated acquisition of multi-dimensional and all-optical information on image, spectrum, and polarization with high resolution and precision. It is based on imaging spectroscopy technology, but integrated with the technique of polarization modulation of light waves. The goals of this research are 1) to set up principle, physical mechanism and mathematical model for simultaneously measuring multi-dimensional all-optical information on image, spectrum, and polarization ; 2) to theoretically analyze the key technical points, identify the potential problems to be solved and possible solutions; 3) to evaluate characteristics and technical parameters of the proposed instrument; 4) to study multi-spectral polarized color image fusion technology for separation, extraction, and integration of information on image, spectrum, and polarization; 5) to design an integrated observation system for detection, identification, and multi-dimensional information fusion of image, spectrum, and polarization; 6) to manufacture, for the first time in the world, a prototype of static imaging polarization spectrometer, which is based on Savart polarizer and can simultaneously measure multi-dimensional information of image, spectrum, and polarization with high resolution and precision; and 7) to simulate space observations of the device in laboratory experiment, and obtain high resolution all-optical information of image, spectrum, and polarization. With all these efforts, a state-of-art information acquisition technology with independent intellectual property will be developed. It is of important significance, and can be widely applied to the Earth's remote sensing and space exploration, as well as military needs.
