Abstract:

A method and apparatus are described for electronically scanning a spherically focused beam in a c-scan mode using a spiral path rather than a traditional raster scan pattern. Essential to the technique is an electronically simulated rotating ultrasonic prism operating according to the general electrical input equation v o exp i omega o t ia cos omega t . The technique allows use of a single delay line with simple connections and no requirements of multiple mixing.
