One of her latest inventions is the Dynamic Bendloss Measuring Device. This device allows for easy and repeatable determination of the bend sensitivity of single-mode optical fibers. It subjects the fiber to dynamically changing bend angles under varying degrees of tension and bend diameters. The device utilizes a swing arm capable of sweeping an arc that subtends a range of angles at any given bend diameter and fiber tension. It calculates the bendloss from the light attenuation at each degree of the range. The varying bend diameters are provided by pins of diverse diameters that are inserted into an adjustably-sized aperture. The variation in the applied tension can be adjusted by changing the input current setting in the tension assembly. With each new pin and tension setting, the swing arm sweeps through the pre-selected range of bend angles, resulting in varying degrees of light attenuation.
Another significant patent is the Distributed Acoustic Sensor. This sensor utilizes a Fizeau type fiber optic transducer and a distributed acoustic collector to gather and return acoustic disturbances from remote areas in buried, underground, or underwater installations. A light beam from a laser or LED source is transmitted over a fiber to a remote transducer, which is coupled to a distributed acoustic collector. The collector may be an extended pipe or tube system filled with an acoustic conducting medium, such as air or an appropriate liquid, which communicates with the sensing diaphragm in the transducer. An interference beam, whose characteristics are a function of the diaphragm motion, is created in the transducer and transmitted back over the common single fiber toward the source. An in-line optical coupler/splitter diverts a portion of the returning modulated beam to a photodetector, which outputs a proportional electrical signal to an electronic circuit for amplification and analysis.
