Abstract:
An ultrasonic laser deflector employing a torsionally oscillating piezoelectric transducer and mechanical transformer is described. A half-wave piezoelectric ceramic is cemented to a half-wave stepped horn to magnify the small amplitude torsional vibrations of the ceramic transducer. The laser is deflected by means of a small mirror machined into the small end of the horn. Design parameters are given which show that large angular displacements are possible at ultrasonic frequencies. A practical design is described, and factors are outlined which influence the use of the device for scanning. Author
