The invention discloses a hyperspectral camera, a hyperspectral imaging device and a control method. The hyperspectral imaging device comprises an optical lens, an entrance slit, a light splitting system, a digital microreflector array, a linear array sensor and a controller, wherein the optical lens is used for collecting reflected light of materials; the entrance slit is positioned at a focal point of the optical lens, so that the reflected light is focused into the entrance slit; the light splitting system is used for splitting the reflected light incident from the entrance slit into a plurality of beams of monochromatic light; the digital microreflector array comprises a plurality of microreflectors, when the plurality of microreflectors are in a first state, the plurality of beams ofmonochromatic light are reflected by means of the plurality of microreflectors and then focused into a light beam line by means of the light splitting system; the linear array sensor is used for receiving the light beam line; and the controller is used for adjusting an operating mode of the digital microreflector array, so as to control a state switching sequence and switching time of the plurality of microreflectors. The hyperspectral imaging device has a low-spectral-resolution and high-speed scanning mode with wavelength arbitrarily selected or combined, and further has the advantage of lowcost.
