A NOVEL ULTRASONIC WAVEGUIDE TECHNIQUE FOR DISTRIBUTED SENSING AND MEASUREMENTS OF PHYSICAL AND CHEMICAL PROPERTIES OF SURROUNDING MEDIA

摘要

This invention relates to a waveguide with distributed sensors that support travelling 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 sensor is operably associated with plurality wave mode for probing and identifying plurality of properties simultaneously. The reflected waves are representative of local information about the surrounding media at that sensor location.
