Abstract

See full text

A system to test operation of an optical sensor is disclosed. The optical sensor includes one or more photosensitive devices configured to convert light to electrical signals. A test light source is included within the housing of the optical sensor. The test light source is periodically pulsed on to emit radiation at a sufficient intensity to saturate each of the photosensitive devices. Each of the photosensitive devices generates a signal corresponding to the intensity of light detected at that device. A logic circuit uses the signals corresponding to the intensity of light to identify whether each of the photosensitive devices is performing at an acceptable level.
