  • The development of third-generation infrared focal plane detectors allows them to respond simultaneously to two different bands of infrared radiation, and the dual-band image brings great benefits to target detection and identification. In this paper, for aerial detection applications, adopting 320×256 dual-color infrared cooled detector, a large-magnification-ratio cooled infrared dual-band zoom optical system with operating bands of 3.7−4.8 μm in the midwave and 7.7−9.5 μm in the longwave has been designed for infrared detection of targets. The optical system adopts a combination of transmissive and refractive structures to realize an optical four-field-of-view switching wide-range zoom, and in order to meet the 100% cold diaphragm efficiency, a secondary imaging mode is adopted. The four-field focal lengths of the optical system are 32 mm, 200 mm, 800 mm, and 1600 mm, and the zoom ratio is 50×. The experimental results show that the optical system is close to the diffraction limit at a modulation transfer function eigenfrequency of 17 lp/mm in each of the dual-band zoom states. The optical system has the characteristics of dual-band, large zoom ratio, large zoom range, fast switching of multiple fields of view, simple and compact structure, and high-quality imaging, which will be widely used in the security fields such as searching, reconnaissance, and so on.
