at the beginning of 2001, professor siwen bi first proposed the new direction of quantum remote sensing at home and abroad. based on the research of fundamental theory and information mechanism of quantum remote sensing, a new concept of quantum spectral imaging was put forward in august 2006. 10 years, quantum spectral imaging research has made breakthrough progress and stage results. firstly, the research status of spectral imaging and the background of quantum spectrum imaging are introduced. secondly, the concept and research methods of quantum spectrum imaging, the relationship between quantum spectrum imaging and spectral imaging and advantages are introduced. the basic theory of quantum spectroscopy is described, especially the research of quantum spectroscopy imaging and quantum spectroscopy. finally, the significance and application prospect of quantum spectrum imaging are described.
