Abstract

PURPOSE: To reduce the fluctuations in a scanning angle by driving the optical system of an ultrared projector with the use of a driving system of torsional vibrations and by supplying the driving energy form a synchronous signal generating source to compensate the phase shift by an automatic phase control and to detect the amplitude of an oscillator thereby to feed back the same to the driving source.
