Abstract
A simple lightweight apparatus for sensing excessive contamination on the faces of an array of light or infrared detectors comprises mounting a light or infrared-emitting diode near one or more of the detectors. When the diode is energized, the associated detectors should detect its radiation, thereby indicating that the detector is operable and that contamination is not excessive.
