Piezoelectric bimorphs are inexpensive and can be applied to a wide variety
of purposes. We took two bimorphs to move one end of a mirror upward (down
ward), and two more piezoelectric bimorphs to move the other end downward (
upward). The new aspect of this approach is that the angle of the mirror is
much larger than that driven by the bending of each bimorph alone due to m
echanical amplification. The optical scanner has a static and nonresonance
mirror rotation of up to 4.6 deg. The power consumption at resonance with m
aximum driving voltage was calculated at 2.6 mW, which we consider to be lo
w power consumption. (C) 2000 Society of Photo-Optical Instrumentation Engi
