Abstract
An optical scanner comprises an optical reflecting means capable of being mechanically displaced to deflect an optical beam for scanning across a target, a driving means for controlling the mechanical displacement of this optical reflecting means, and a storage means for storing digitized data of a driving signal having a predetermined waveform which is set depending on the mechanical characteristics of the optical reflecting means and driving means. The digitized data are sequentially read out and converted into analog signals to drive the reflecting means. This arrangement makes it possible to produce a desired driving waveform which can prevent the overshooting of the reflecting means when it reverses its motion.
