<P>PROBLEM TO BE SOLVED: To provide an actuator device for optical deflector, which has a small and simple configuration and is capable of reducing speckle noise which is caused when a light beam from a light source such as laser beam source is scanned to display an image. <P>SOLUTION: Piezoelectric actuators 42a, 42b supported by a support 40 translate and vibrate a base 43 on which an optical deflector deflecting light from a light source is mounted, and create a very small optical path difference in the light reflected by the optical deflector. <P>COPYRIGHT: (C)2011,JPO&INPIT |
