Abstract
A light deflecting device includes a first optical element, a vibration applying part at an incident end portion of the first optical element and vibrating an emissive end portion of the first optical element along a first direction, and a second optical element moving along a second direction different from the first direction with a speed lower than a speed of the first optical element.
Claims16
A light deflecting device comprising:
- a first optical element;
- a first actuating part disposed at an incident end portion of the first optical element and configured to vibrate an emissive end portion of the first optical element along a first direction;
- a second optical element disposed over the emissive end portion of the first optical element;
- a second actuating part configured to move the second optical element along a second direction different from the first direction with a speed lower than a speed of the first optical element;
- a third actuating part configured to move the second optical element along a third direction different from the first and second directions;
- and
- a fixed base part disposed at the incident end portion of the first optical element,
- wherein the first actuating part is disposed on the fixed base part.
