ABSTRACT:
An optical anti-tamper system including a light emitting layer located within a chassis, a light detecting layer located within the chassis and one or more detectors optically coupled to the light detecting layer. The one or more detectors are in communication with an alarm. The alarm is operable to transmit a tamper-event warning signal if an increased light level is detected by at least one detector.
