Abstract
A scene imaging system (SIS) integrity monitor for monitoring the required operation of an imaging sensor of an SIS. The SIS is of a type including: i) an imaging sensor, ii) an imaging system processor, and iii) an imaging system display. The SIS integrity monitor includes a signal emitter assembly for receiving emitter drive signals from an imaging system processor and directing a monitoring image into the active field of view of an imaging sensor for sensed image generation. The generated image is provided to the imaging system processor for analysis. The imaging system processor evaluates the location and modulation state of the generated image to determine if faults exist in the image generation or image display paths.
