Abstract :
MEMS technology has been widely used to realize optical scanners. However, the actuation principle has been so far limited to conventional principles and the size of the mirror limited below 1 mm/sup 2/. If magnetostriction is used for the actuation and the size of the mirror is tens of mm/sup 2/, this will allow for industrial applications. The work stresses the new scanner design for obtaining large deflection angles and higher structural strength.
