Abstract:

This paper proposes an engineering technique for selecting the diameter and focal length of the lenses of modern high-sensitivity thermal viewers in order to provide the devices with a specified acquisition range and threshold sensitivity. The technique can be implemented by accumulating signals with very low values of the noise-equivalent temperature difference, at which the efficiency of these devices is no longer limited by the singal-to-noise ratio but by the contrast sensitivity of the operator’s visual analyzer.

Keywords:

thermal viewer, acquisition range, diameter, focal length of lense
