Abstract

PURPOSE:To keep almost constant the amplitude even with temperature changed, by applying high-frequency driving signal to a piezoelectric oscillator to which a mirror is sticked integrally and finely oscillating the light flux reflected by the mirror through fine oscillation in bending oscillation mode. CONSTITUTION:The system consisting of a piezoelectric oscillator 7 and a mirror 6 is oscillated in the mode as shown in Figure, and the points C and D shown nodes. Thus, in case of oscillation with this mode, the part covered with the exciting electrode 22 of the piezoelectric oscillator 7 and the part covered with the detection electrodes 21a, 21b of the 1st and 2nd are oscillated entirely with the same amplitude, the same oscillation and the same phase. Thus, the detection signal (a) is transmitted from the 1st and 2nd detection electrodes 21a, 21b with the piezoelectric effect, and the voltage is maximum when the amplitude is maximum, that is, it is maximum at the resonant frequency. The phase of this detection signal (a) is adjusted so that positive feedback system can be obtained with the phase shifter 25, allowing to excite the resonance frequency light deflector 5.
