摘要： A fiber optic system (10, 210) including a plurality of optical sensors, each with an identification system (20, 120, 220, 320). The fiber optic system (10) includes a fiber (12, 112) extending a distance, a demodulator (14), and at least one coupler (16, 116), optical sensor (18, 118) and corresponding identification system (20, 120). The identification system (20, 120) is powered by light shunted from the fiber (12, 112) by the coupler (16, 116) to a modulating device (24, 124). The modulating device (24, 124) modulates the light and transmits it to a power converting device (16, 116), which transforms the light energy into electrical energy. The electrical energy powers a high temperature integrated circuit (28, 128) upon which is stored a digital identification of a respective optical sensor (18, 118). The integrated circuit (28, 128), upon being powered up, sends a modulated response (30, 130) back up to the surface through the modulating device (24, 124). Alternatively, a passive identification system (210) is described, where reflective devices (220, 320) are placed at pre-determined locations along the length of the fiber (212, 312). As the optical beam passes through the reflective devices (220, 320), identification information for a sensor (218, 318) is encoded onto the beam. An optical frequency domain reflectometer (214) generates the optical beam and detects the encoded information.
