Comportement d'un recepteur thermique d'image sous vide partiel
Abstract
The transfer characteristics of thermal image detectors depends on the air pressure around them. Increasing pressure causes a decrease of the sensitivity at zero frequency but simultaneously broadens the spatial frequency response. These results allow us to assess the significance of experiments made at atmospheric pressure.
