红外地物波谱仪是一种野外携带式红外分光辐射仪器,用于测量各种地物目标的光谱辐射特性,为航片及卫片的判读提供波谱辐射基准。也可测量军事目标及背景的波谱辐射参数,为目标的识别和伪装提供依据。它既可在8～14μm波长范围内进行连续光谱测量,也可在此波长范围内对任何波长点进行定点测量,且可测量目标绝对温度。该仪器的光学系统设计成目标光路、机内基准黑体光路及可见光瞄准光路三个光路同轴的双视场光学系统。机内基准黑体为恒温平面型黑体,使基准黑体的辐射能量为常数,便于标定和测量计算。测得的目标光谱辐射信号经过CMC-80单板机进行运算及数字化处 Infrared feature spectrometer is a portable portable infrared spectroradiometer, used to measure the spectral radiation characteristics of a variety of objects, to provide aerial and satellite interpretation of spectral radiation benchmark. It can also measure the spectral radiation parameters of the military target and the background, and provide the basis for identifying and disguising the target. It can be in the continuous spectrum of 8 ~ 14μm wavelength range measurement, but also in any wavelength point within the wavelength range of fixed-point measurements, and can measure the target absolute temperature. The optical system of the instrument is designed as a target optical path, a reference black body optical path in the machine and a visible optical path optical path of three optical paths of a coaxial dual-field optical system. The benchmark blackbody is a constant temperature planar blackbody, which makes the radiation energy of the benchmark blackbody constant, which is convenient for calibration and measurement calculation. The measured target spectral radiation signal is processed and digitized by the CMC-80 single board computer
