Abstract
Official abstract text for this publication.
A vibrating mirror element includes a drive control portion configured to control the driving of a correction drive portion to keep the turning angle velocity of a mirror portion substantially constant by oscillating the mirror portion about an axis at a non-resonance frequency in a direction opposite to a direction in which a resonant drive portion oscillates the mirror portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A vibrating mirror element comprising: a mirror portion capable of being oscillated about an axis; a resonant drive portion resonantly driven at a resonance frequency to resonantly drive the mirror portion by oscillating the mirror portion about the axis; a correction drive portion provided outside the resonant drive portion to be capable of oscillating the mirror portion about the axis, configured to non-resonantly drive the mirror portion by correcting…
