  • Fiber optic security system including a fiber optic seal and an electronic verifier
    Patent number: 4447123
    Abstract: The present invention includes a fiber optic seal (2) including a transparent seal body (4) having two spaced apart cavities (12,14,52,54) formed therein. Both ends (36,38) of a fiber optic cable (28) are respectively secured within the spaced apart cavities (12,14,52,54). A microprocessor-based electronic verifier (60) injects light into one of the cable ends (38) via a plurality of illumination light guides (20) fixed within the seal body (4) between an external surface (6) thereof and the illumination cavity (12). Light emitted from the remaining end (36) of the fiber optic cable (28) is transmitted from the detection cavity (14) to the exterior surface (6) of the sealed body (4) via a plurality of detection light guides (24) fixed within the seal body (4). Thereafter, the light is measured and converted by the electronic verifier (60) to provide a seal signature.
