Filed: 1994-02-14
Abstract: PURPOSE:To select cycles of magnetization and obtain an optional scanning period, and to easily make a short-cycle, large-amplitude scan by providing an exciting means which magnetizes an extended member to the different polarities alternately and periodically. CONSTITUTION:In a structure 2, exciting coils 6 are provided across the extended member. The exciting coils 6 are constituted by winding cores with coils and supplied with AC currents of constant frequency f0 from an AC source 7 coupled electrically with the coils to magnetize the extended member 3 into the N pole or S pole periodically by inversion according to the frequency f0. The repetition of the magnetic pole inversion causes the extended member 3 to vibrate in a uniaxial direction at a constant period through the attraction and repulsion of the magnetic poles of a fixed magnet, and a scanner mirror which is fixed at the top of the member is driven to make a scan with laser light. The vibration is caused by the magnetic pole relation with the fixed magnet, so an optional scanning period is obtained by selecting cycles of magnetization and the short-cycle, large-amplitude scan can easily be made.
