The invention discloses a hyperspectral imaging device based on rotary high-speed spectrum channel switching. The hyperspectral imaging device comprises a high-speed light splitting device, an imaging unit, a right-angle reflection lens, a computer, a signal acquiring and processing module and the like. The high-speed light splitting device is arranged between the imaging unit and the right-angle reflection lens and processes light entering the right-angle reflection lens to acquire corresponding monochromatic light, successively focusing the monochromatic light on the imaging unit to obtain a series of spectrum images. The high-speed light splitting device and the imaging unit are connected with the computer through the signal acquiring and processing module. While greatly increasing spectrum channel switching speed and achieving high-speed spectrum scanning, the hyperspectral imaging device decreases the momentum disturbance, the jitter, and the power consumption of a whole system to the utmost extent and increases the reliability of the system obviously. Angular speed can be increased at will so that each optical filter acquires multiple sequences while allowing exposure, thereby improving system synchronism and increasing the signal-to-noise ratio of the image.
