Modeling of characteristics of array photodetecting device in composition with the thermal imaging system

摘要

Multielement photodetectors have a considerable spread of sensitivity between the elements, and that leads to the noise appearance on the output image due to the difference of output elements voltage at similar parameters of irradiated signal. In order to exclude the pointed image defects they used different methods of channel sensitivity equalization. At that we should notice that the efficiency of such equalization depends in many respects on the parent voltage sensitivity range of multielement photodetector.
