Abstract: A wide-field imaging and hyperspectral collaborative early warning system and method are provided. The system includes: a primary imaging system, a digital micromirror array, a first collimation system, a second collimation system, a first reflector, a second reflector, a wide-field imaging optical filter, a narrow-band optical filter, a wide-field imager and a hyperspectral interferometer. The system and method have the advantages that the wide-field imaging general survey and fine spectrum detection can be realized synchronously, the functions are multiple, and the false alarm rate is low; the target spatial resolution of the fine spectrum identification is adjustable, the micro-control unit flipping solution is simple to operate, and quick adjustment is realized; the adaptability is strong, the flipping time of the corresponding micro-control unit is adaptively adjusted for the measured target with too low or too strong radiation intensity, and the dynamic range of the system is effectively improved.
