Abstract

The invention relates to a miniature roll-up long-wave refrigeration optical system. A fairing, a front lens group, a folding reflecting mirror group and a rear lens group. The front lens group comprises a first lens and a second lens; the folding reflecting mirror group comprises a reflecting mirror I and a reflecting mirror II; the reflecting mirror II and the reflecting mirror I are arranged inparallel; the rear lens group comprises a third lens, a reflecting mirror III, a fourth lens, a fifth lens, a sixth lens, detector protection glass, a cold light stop and an image plane; the light rays reflected by the reflecting mirror II pass through the third lens to the reflecting mirror III; the reflecting mirror III and the reflecting mirror II are vertically arranged; and the fourth lens,the fifth lens, the sixth lens, the detector protection glass, the cold light stop and the image plane are orderly coaxially arranged along the transmitting direction of the light rays reflected by the reflecting mirror III. The miniature roll-up long-wave refrigeration optical system in the invention belongs to the technical field of optical imaging and has the characteristics of high resolution,large relative aperture, strong light gathering capability, compact structure, small volume and light weight.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to a miniaturized high-resolution rolling-upward long-wave infrared cooling optical system for imaging guidance. Background technique [0002] Air-to-air combat missiles have the characteristics of large search range, fast tracking speed, and strong maneuverability. The most representative fourth-generation infrared air-to-air missiles in the world are the American AIM-9X and the European infrared IRIS-T. . Among them, the AIM-9X seeker has been equipped on F16, F22 and other fighters. Its working band is 3-5μm. It adopts Stirling cooling detector. The fairing is made of sapphire material with higher mechanical strength and better aerodynamic performance. With higher sensitivity and spatial angular resolution, it can better complete the search, identification, capture and tracking of targets, give target position information, and implement precise strikes. At ...
