reportActive / Technical Report | Accession Number: ADD008072 | Need Help?

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. The technique allows use of a single delay line with simple connections and no requirements of multiple mixing.
