The Hybrid Refractive-Diffractive Optical System Design of Preposition of Aperture LWIR

摘要：

The LWIR (Long Wave Infrared) used for observation heat. The influence of background radiation caused the sensitivity of the system decreased. The article uses subzero refrigeration detector, and require the efficiency of luminescence railing reaching 100％. The paper deduce the design formula of preposition of aperture LWIR, and the wave band 10~12μ m, diameter 50mm, F/2, field 8.20×8.20. This paper based on the principle of binary diffractive optical elements, the unique dispersion properties have the incomparable advantage compared with traditional optical components in calibration system. Design results show that the hybrid refractive-diffractive Optical System compared with the traditional infrared optical system, not only use the fewer optical elements, and achieve the purpose of the lightweight, and the system performance also have significantly improved.
