The invention discloses a total reflection wide band multi-spectral imaging system which belongs to the technical field of imaging spectroscopy. The system consists of a pre-reflective imaging objective lens, reflective filter imaging, filter control, focal plane array detector imaging, data processing and a system. The total reflection wide band multi-spectral imaging system provided by the invention can simultaneously detect the two-dimensional high spatial resolution image and multi-spectral image of a target in the working range of ultraviolet and near infrared, overcomes the problems of aberration, chromatic aberration, registration and the like of the introduction of a transmission filter of a conventional transmission filter type multi-spectral imaging system, overcomes the problems of slit and low luminous flux and spectral sensitivity in a traditional grating spectral system, and can be widely used in spectral color high-fidelity reproduction, wide-band print quality detection, biomedical multi-spectral imaging, multi-spectral remote sensing and other fields.
