Title:
OPTICAL DEFLECTOR
Document Type and Number:
WIPO Patent Application WO/2015/040956
Kind Code:
A1
Abstract:
Provided is an optical deflector that is capable of enlarging the rotation angle of a reflecting surface. A rectangular-frame-shaped support part (20) that surrounds a movable plate (10) has a pair of first parallel parts (22) that are arranged parallel to each other, and a pair of second parallel parts (26) that are perpendicular to the first parallel parts (22) and arranged parallel to each other. One end (33) of a torsion bar (30) is connected to the movable plate (10), and another end (34) is connected to the first parallel parts (22). An optical deflector (1) is provided with a first voltage actuator (40) that is provided to the first parallel parts (22) and that oscillates the first parallel parts (22) and with a second voltage actuator (50) that is provided to the second parallel parts (26) and that oscillates the second parallel parts (26).
