Description
Summary:The field of restorative dentistry and the problem of ultrasonic airframe corrosion in aerospace are introduced as motivation for the construction of a miniature ultrasonic pulser/receiver. === A broadly applicable ultrasonic pulser and receiver system is developed. Two pulsers, a 5V square and a 100V spike, and a 52dB amplifier with a 57MHz 6dB bandwidth were constructed as a result. These battery powered devices are tailored for compatibility with a custom built wireless data transmission system, also driven by the same voltage. It is demonstrated that the new pulser/receiver is comparable to the commercial system in performance in certain areas. === The new pulsers/receiver and a commercial one are used in this work. The data is acquired and analyzed using LabView and Matlab. It is shown that the ultrasonic technique can be used to follow the reaction in time as well as to gauge the cure of dental composites. The current work in ultrasonic airframe corrosion detection is furthered and the wireless system's functionality is affirmed.
