ULTRASONIC WAVEGUIDE TECHNIQUE FOR DISTRIBUTE SENSING AND MEASUREMENTS OF PHYSICAL AND CHEMICAL PROPERTIES OF SURROUNDING MEDIA

摘要

This invention relates to a waveguide with distributed sensors that support traveling ultrasonic wave modes to provide quantitative local distributed sensing of the physical and chemical properties of the medium surrounding the sensor locations and/or the material properties of the waveguide. The plurality of sensors is operably associated with a plurality of wave modes for probing and identifying a plurality of properties simultaneously. The reflected waves are representative of local information about the surrounding media at that sensor location.
