However, the existing hyperspectral cameras have obvious limitation in the aspect of band coverage, and are difficult to meet the urgent demands of the continuously developed scientific researches and practical applications on broadband hyperspectral imaging. Currently, the band coverage of most hyperspectral cameras is relatively narrow, and the common band interval can be divided into 400nm to 1000nm, 900nm to 1700nm, 900nm to 2500nm, and the like.
