An optical display system includes a first display, a plurality of electronic drivers, a controller, and a combiner. Light from a scene is combined with image light from the first display, and the combined light presented to an observer. The combiner includes an electrochromic layer comprising one or more electrochromic regions disposed between the scene and the combiner. The electronic drivers are arranged to electrically connect with and drive respective of the electrochromic regions. The controller is configured to control the plurality of electronic drivers to individually address each of the electrochromic regions to selectively drive some of the electrochromic regions to change light transmission of the selectively driven electrochromic regions.

Optical display system with regionally addressable electrochromic light modulator

An optical display system includes a first display, a plurality of electronic drivers, a controller, and a combiner. Light from a scene is combined with image light from the first display, and the combined light presented to an observer. The combiner includes an electrochromic layer comprising one or more electrochromic regions separated from each other. The electronic drivers are arranged to electrically connect with and drive respective of the electrochromic regions. The controller is configured to control the plurality of electronic drivers to individually address each of the electrochromic regions to selectively drive some of the electrochromic regions to change light transmission of the selectively driven electrochromic regions.

An integrity monitoring system for a first image sensor includes an electronic processor configured to receive sensor data for the provision of image data associated with an environment of the avionic sensor. The electronic processor is configured to monitor the avionic sensor for integrity. The electronic processor is configured to perform at least one of: determining a presence of an optical feature associated with optics of the first image sensor, comparing overlap information derived from the sensor data and other sensor data, comparing characteristics of a digital output stream of the sensor data to expected characteristics, or comparing a first motion derived from the image data and a second motion derived from avionic position equipment.
