| Abstract: | An LWIR continuous zooming system based on long-wave cooled 384×288 focal plane array (FPA) detector with large zooming range is described in this paper.. The system consists of eight lenses and two reflectors, the operating wavelength is 7.7-9.3 μm, F number is 3, and the zoom ratio is 25:1, which satisfies 100% cold shield efficiency. The system is optimized by using the CODE V optical design software. The design results proved that the system has the advantages of simple structure, large zooming ratio, small size and excellent image quality. |
