    A triple imaging infrared continuous zoom array detector scanning optical system is proposed. On the basis of traditional infrared secondary imaging optics, a continuous zoom telescope system is added. Continuous zoom is realized by moving the zooming group and the compensating group along the optical axis. In the middle parallel light path, a galvanometer is introduced, and the galvanometer is used to scan back in the corresponding angle range at a specific frequency, which can compensate for the object movement during the exposure time caused by the rotation of the scanning platform, and keep the image clear and stable during the rotation scanning without any shadow. A 60~360 mm continuous zoom optic system is designed. Optic distortion is smaller than 0.5% at all effective focal length. The system achieved good performance after testing, and can be widely used in the infrared search and tracking system.
