大口径宽视场双波段扫描红外相机光学设计

Optical design of Infrared scan camera with large aperture,wide field of view and dual wave-band

通过分析计算,设计了一种大口径宽视场折射式红外相机光学系统。该系统设计用于超长线阵扫描红外相机的地面演示成像,它能同时对短波2μm—3μm、中波3μm—4.5μm双波段成像,且同时具有24°的大视场和150mm的宽口径,成像质量接近衍射极限。该系统在航天遥感领域应用广泛。

A new Infrared scan optical system with large aperture and wide field is designed.It can image in short-wave(2μm—3μm)and mid-wave(3μm—4.5μm)simultaneously.Its field of view reaches 24°.The image quality is approximately to diffraction limit over full field of view.It can be applied to space remote-sensing systems.
