摘要
Abstract
A set of common aperture optical system with dual bands is presented for 640×512 MWIR and 1920×1080 CCD. The system works in the wavelength ranges of 3.6-4.8 μm and 0.45-0.9 μm and in the environment temperature range of -40℃-60℃. The TV system has an effective focal length of 500 mm, field of view of 0.38°×0.43°, and an F/#of 4; the IR system has a focal length of 600 mm, the field of view of 0.38°×0.43°, an F/#of 4.8, and a cold shield efficiency of 100%. The system takes advantage of Cassegrain system. The beam splitting of the IR/VR is achieved by using a spectroscope and the aberrations are reduced by using respective correcting lenses. The system obtains good image quality for temperatures lying between -40℃-60℃, and can recognize the long-distance targets.关键词
