Improvement of thermographic imaging device by using an automatic scanning system as opaque for infrared radiation of a matrix aperture with a window of transparency at the lens of the thermal imaging lens, leads to improvement of the spatial and temporal characteristics of the thermal imager, namely, its separation from the point of view. As a result of the experiments, it was found that the spatial resolution of the improved thermographic method (compared to the standard method of determination) was improved by 15 – 20%, and the spectral resolution by 0.3 – 0.5 μm. According to the results of the analysis of the processed image, the adjusted temperature scale of the thermogram, which, in turn, allowed to increase the accuracy of temperature determination in each accurate image (the temperature distribution error did not exceed 5.5%).
