Portable infrared spectral radiance measurement apparatus based on PbSe detector

A portable infrared spectral radiance measurement apparatus without the cooling based on PbSe detectors is designed to measure the spectral radiance of the object in the wavelength range from 2.1 to 4.1 \mu m. Cores Luxell 256 module is applied which integrates 256 pixel line array PbSe detectors, a
