摘要/Abstract

摘要： 分子Faraday旋光红外滤波成像器件是一种具有梳状离散透射谱的新型滤波器件。该器件透射光谱由分子能级跃迁决定，因而同时具备高光谱分辨能力及高光学稳定特性。通过顺磁性分子的Faraday旋光效应研究，建立分子Faraday滤波器件的理论模型，并利用量子级联激光光谱技术对滤波器件进行了谱型测试；探讨该技术在红外成像探测系统中的应用，进行基于Faraday旋光红外滤波成像技术的燃烧诊断初步试验，获得了燃烧环境中不受H₂O红外辐射影响的纯NO图像。试验结果表明， Faraday旋光红外滤波成像技术在红外成像遥感探测，尤其是燃烧系统微量成分探测中具有较强的实用性和明显的优越性。

Abstract: Infrared molecular Faraday imaging filter (MOFIF) is a novel type of filtering device with comb-like discrete transmission spectrum. Its transmission spectrum is determined by the energy level transition of the molecule, which provides both high spectral resolution and high optical stability. A theoretical model of molecular Faraday optical filter (MFOF) is established by studying Faraday optical rotation effect. And the transmission spectrum of MFOF is measured by using a quantum cascade laser spectrum technology. The application of this technology in infrared imaging detection system is discussed. Preliminary experimental study on combustion diagnosis based on infrared MOFIF technology is also conducted. Pure NO images uninfluenced by H₂O infrared radiation were captured in the combustion environment. The experimental results show that MFOF has strong practicability and obvious superiority in infrared imaging remote sensing detection, especially in the detection of trace components in combustion systems.
