Abstract
Systems and a related method for monitoring commercial off the shelf (COTS) display devices in an avionics display system ensure that the COTS display devices are compliant with hazard classifications by positioning transparent photodetectors in the optical path to monitor the images and components generated and projected by the COTS display devices. Transparent photodetectors are positioned downstream in the optical path to monitor image orientation, refresh rate, or brightness of displayed images and image elements. The system may include transparent image sensors for capturing scene content and monitoring image integrity by comparing the captured scene content to the displayed images. Transparent image sensors positioned proximate to camera cores of an enhanced vision system (EVS) may verify the alignment of individual component image streams combined into an image stream displayed via HDD, HUD, HWD, or a like display element.
