Description
Summary:The paper describes a fully automated system for measurement of the ultrasonic signals generated by ultrasonic transducers, designed for operating in air for a frequency range from 40 to 300 kHz. Study of new material's properties and sensitivity patterns for bio-mimetic ultrasonic transducers will be made. Measurements to estimate other important parameters of transducers will be possible as well. The system is designed as a computer controlled four axis system, where one element (usually transmitter) can be positioned in XYZ space and the other element (receiver) can be rotated around its axis. The relative position between transmitter and receiver is controlled by specialized software running on a personal computer. The system is flexible, in the sense that it supports any kind of materials and environment media for testing and can be driven from distance via internet.
