Abstract

PURPOSE:To obtain high relative resolution and response speed, by exerting the power of piezoelectric element group which is expanded and contracted by AC voltage, to the position symmetrical with respect to the axis of rotation of a rotating mirror body having plane reflecting mirrors attached to the face and back sides, to vibrate it, and emitting incident laser beam into the face reflecting mirror from the back reflecting mirror through an external reflecting mirror. CONSTITUTION:A rotating reflecting mirror body 3 having plane reflecting mirrors 2A, 2B can rotate around the axis of rotation 4A. Two points symmetrical to the axis of rotation 4A of the rotating reflecting mirror body 3 are linked to piezoelectric element groups G, G' by way of two bar rods 15, 17. AC voltage from a electric power source 19 is alternately applied to the piezoelectric element groups G, G' in the same phase. The piezoelectric element groups G, G' which are secured at ends H, H' are alternately expanded and contracted in phase, so that the rotating reflecting mirror body 3 is rotated and vibrated at small angle around the axis of rotation 4A. The laser beam LA entering the reflecting mirror 2A is reflected by reflecting mirrors 26, 28, 29, 2B, and is emitted. Since the angle of deflection is doubled in each reflection, high resolution and response speed may be obtained.
