Abstract
A circuit for coupling infrared detector elements maintained in the cryogenic environment with a processing circuit maintained at a substantially higher temperature is disclosed. The circuit comprises a detector output sampling/comparing circuit electrically connectable to an associated detector element. The sampling/comparing circuit is disposable in a cryogenic environment along with the associated detector element. The circuit is constructed to receive power from a power source that is electrically and thermally isolated from the sampling/comparing circuit. The output of the sampling/comparing circuit being communicatable to a processing circuit while remaining electrically and thermally isolated therefrom.
