A kind of multi-field of view (multi-FOV) hyperspectral imaging system based on mid-wave infrared (MWIR) has been developed for the first time, to the best of our knowledge. The hyperspectral imaging system is based on two focus length which can be used in different situation. According to the theory of zoom optics and the design method of infrared optics, the front telescope zoom system is calculated and designed, which is coupled with the acousto-optic tunable filter (AOTF) and the focus system to realize the infrared zoom optical system. By developing and optimizing the focus system and the MWIR detector, the +1-order diffracted light and 0-order light of AOTF can be clearly imaged on image plane. So that it can output the MWIR thermogram signal and spectrum signal at the same time. The experimental results show that the system can clearly image the target with 8km away. And the IFOV is up to 0.066mrad. The results pave the way to a novel spectrum detect technology based on infrared zoom optical system.
