Integrity monitoring systems and methods for image sensors

An integrity monitoring system, comprised of:

• optics having at least one optical feature;
• a first image sensor for producing first sensor data;
• a second image sensor for producing second senor data;
• and
• an electronic processor configured to receive said first and second sensor data as a digital stream and to:
• a. compare the presence of an optical feature associated with the optics of the first image sensor in said sensor data and comparing the location or shape of the optical feature with the expected location to determine the integrity of the first image sensor;
• b. compare overlap information derived from the sensor data and from said second image sensor to determine the integrity of the first image sensor;
• and
• c. compare the characteristics of said digital stream of the sensor data to the expected characteristics to determine the integrity of the first image sensor.
