摘要
针对远距离高温目标多光谱辐射测温的需求,设计了一款多通道光谱探测系统.系统前端采用同轴两反卡塞格林式结构收集目标光谱辐射,后端包括用于目标定位的长波红外成像瞄准系统和分别工作在380～1050 nm、980～2550 nm双波段光谱系统.光谱系统采用Cz-erny-Turner结构,在380～1050 nm波段分辨率优于5 nm,980～2550 nm波段分辨率优于15 nm,光谱通道数量大于220个.400 m目标外场实验和700～2300 ℃高温黑体温度实验表明,多通道光谱探测系统能够进行远距离目标的瞄准和光谱探测.本文设计的多通道光谱探测系统有望用于地面、航空及航天等远距离的温度探测.
Abstract
In this paper,a multi-channel spectral detection system is designed to address the need for multi-spectral radiometric temperature measurement of high temperature targets over long distances.The front end of the system uses a bi-reflective Cassegrain structure to collect the spectral radiation of the target,while the back end includes a long-wave infrared imaging targeting system for target location and a dual-band spectral system operating at 380～1050 nm and 980～2550 nm respectively.The spectral system adopts Czerny-Turner structure,with a resolution better than 5 nm in the 380～1050 nm band and 15 nm in the 980～2550 nm band,and the number of spectral channels is grea-ter than 220.The 400 m target outfield experiments and the 700～2300 ℃ high temperature blackbody temperature experiments show that the multi-channel spectral detection system is capable of targeting and spectral detection of long-range targets.The multi-channel spectral detection system designed in this paper is expected to be used for long-range temperature detection on the ground,in aviation and in space.
