大视场透射式红外平行光管系统设计

为了满足红外检测设备大视场、高像质、易便携的要求,设计了工作波段为8~14 μm 、全视场大于等于24°、孔径为130 mm的大视场透射式红外平行光管系统.采用三片式摄远物镜结构,并加入一片非球面解决了三片透射式系统像差难以平衡的难题.根据光学设计理论对系统进行多层次优化设计,最终得到了在全视场内的红外平行光管设计结果,其中不同波长所对应的各焦距位置在20 lp/mm处的调制传递函数不低于20％、畸变小于1％,其优点是大视场、高分辨率、成像质量好、结构简单,可以为各种红外热像仪、军用红外瞄具的性能参数检测系统提供高像质、高分辨率的无穷远红外目标源.成功研制一台应用样机,并于加工装调后进行了应用验证试验,结果表明样机获取图像清晰准确,能够满足测试要求.

Abstract

In order to meet wide-field,high image quality and easy portability of infrared detection equipments,a large field transmissive infrared collimator system with working band of 8~14 μm,full field ≥24 °,aperture of 130mm was designed.A simple three-type telephoto lens structure and a non-spherical were used to solve the problem that how to balance the three transmission systems aberration.According to the theory of optical design optimization of multi-level system design,eventually a infrared transmissive collimator system was obtained, the MTF at 20 lp/mm was not less than 20%,distortion resolution rate infinity was less than 1% in the whole field of view and the position of each focal length corresponding to different wavelengths.The advantages are wide field of view,high resolution,good image quality and simple structure,which can provide high image quality,high-resolution infrared target source at infinity for a variety of infrared imaging,military infrared detection system performance parameters sights.A prototype application was developed and applied to verify alignment test.The results show that the prototype can get clear and accurate images to meet testing requirements.
