摘要：
The invention relates to an ultra-weak light multispectral imaging method and an ultra-weak light multispectral imaging system, which can realize multispectral two-dimensional imaging of an ultra-weak light object by constituting a linear array from single-photon detectors of all response wavelengths and combining it with light-splitting technology. The ultra-weak light multispectral two-dimensional imaging system realizes high-resolution optical modulation by adopting the compressive sensing (CS) theory and the digital light processing (DLP) technology and using a linear array single-photon detector as a detection element the ultra-weak light multispectral two-dimensional imaging system comprises a light filter (6), a first lens (1), a DMD control system (7), a second lens (2), a spectrophotometer (3), a linear array single-photon detector(4) consisting of a plurality of single-photon detectors with different response wavelengths, and a central processing unit (5) and the sensitivity of the system can reach the single-photon level. The invention can be widely applied in the fields of biological self-illumination, medical diagnosis, nondestructive material analysis, astronomical observation, national defense and military, spectral measurement, quantum electronics and the like.
