MULTIPLEXING FOR FIBER-OPTIC SENSORS

FIBER OPTIC SENSORS HAVE BEEN DEVELOPED FOR A VARIETY OF INDUSTRY MONITORING AND CONTROL APPLICATIONS. FULLY REALIZATION OF THE POTENTIAL CAPABILITY OF THE FIBER OPTIC INTENSITY SENSORS, HOWEVER, REQUIRE INNOVATIVE APPROACHES TO PRACTICAL IMPLEMENTING METHODS TO MULTIPLEXING THE INTESITY SENSORS INTO FIBER OPTIC DATA NETWORKS. A NOVEL WAVELENGTH DIVISION MULTIPLEXING TECHNIQUE ON A UNIQUE DEVICE, THE ACOUSTIC-OPTIC TUNABLE FILTER (ACTF), IS DESCRIBED IN THIS PROPOSAL. PHASE I EFFORT OF THE PROPOSAL PROGRAM INCLUDES A SYSTEM ANALYSIS AND EXPERIMENTAL INVESTIGATION OF THE PROPOSED TECHNIQUE TO DETERMINE THE PRACTICAL LIMITS OF ACCURACY, REPEATABILITY AND MULTIPLEXING CAPABILITY OF THE FIBER OPTIC SENSORS.
