Newly developed, high-performance, long-wave- and mid-wave-IR Dyson spectrometers offer a compact, low-distortion, broadband, imaging spectrometer design. The design is further accentuated when coupled to microbolometer array technology. This novel coupling allows radiometric and spectral measurements of high-temperature targets. It also serves to be unique since it allows for the system to be aligned warm. This eliminates the need for cryogenic temperature cycling. Proof of concept results are shown for a spectrometer with a 7.5 to 12.0 μm spectral range and approximately 20 nm per spectral band (~200 bands). Results presented in this Letter show performance for remote hot targets (>200 °C) using an engineering grade spectrometer and IR commercial lens assembly.
新开发的高性能长波和中波红外 Dyson 光谱仪提供了紧凑、低失真、宽带、成像光谱仪设计。当与微测辐射热计阵列技术结合使用时，这种设计进一步得到了强调。这种新颖的耦合允许对高温目标进行辐射测量和光谱测量。它的独特之处还在于它允许系统在温暖的状态下进行对准。这消除了对低温温度循环的需求。本文展示了一个具有 7.5 至 12.0 μm 光谱范围和约 20 nm 每个光谱带（约 200 个带）的光谱仪的概念验证结果。本文介绍的结果表明，使用工程级光谱仪和商用红外透镜组件，可以对远程热目标（>200°C）进行测量。
