- This paper demonstrates how to perform hyperspectral infrared measurements with uncooled thermal camera and imaging spectrometer. Such thermal cameras are sensitive to wavelengths in the range of 7 – 14 µm (LWIR). There is a description of a diffraction grating based spectrometer with Czerny-Turner optical configuration. To perform hyperspectral acquisition of thermograms it is required to have the camera synchronized with spectrometer, so that recorded frames correspond to known wavelengths. For this purpose the dedicated software was developed and it is also described in this paper, with its operation algorithm. There is a problem of thermal camera drift, and this paper proposes the solution to deal with it. Moreover a description how to obtain transmission plot and exemplary results is presented with the description of measurement rig. In addition, noise related issues are covered and discussed.
