The image quality during the device
operation at below zero temperatures is
worse than at positive temperatures
Possible cause
Because of variations in thermal conductivity, objects (surrounding
environment, background) under observation become warm more
quickly at above-zero temperatures, which allows higher temperature
contrast, so the quality of the image produced by a thermal imager will
be better.
At low operating temperatures, objects under observation (background)
normally cool down to roughly identical temperatures, which leads to
reduced temperature contrast and to image quality (precision)
degradation. This is normal for thermal imaging devices.
