Abstract
A method includes determining a signal current based on an average current associated with one or more detectors. The method also includes determining a strip voltage based on the signal current. The method further includes biasing a strip resistance with the strip voltage. The biasing of the strip resistance creates a strip current. The method additionally includes biasing a detector array with a detector voltage. The biasing of the detector array creates a detector current. The method also includes determining levels of incident radiation from a scene based on the strip current and the detector current.
