Abstract:
1. A tamper detection system comprising: a continuous optical fiber path disposed in a medium which is part of or associated with a container and enclosing a volumetric space of the container, a light source optically coupled to one end of the optical fiber path for introducing light into the optical fiber path; a light detector optically coupled to the other end of the optical fiber path for receiving light from the optical fiber path; a circuit connected to the light detector and operative to detect an absence or a decrease in the light from the optical fiber path and to provide an indication thereof; a plurality of sensors, each sensor being optically coupled to the optical fiber path and operable to detect an associated condition inside the container and to affect the light received by the light detector in response to detecting the condition; and a circuit coupled to the light detector and operable to generate an alarm signal if at least one detected condition exceeds a predetermined value.
