LIGHT DEFLECTOR
Document Type and Number:
WIPO Patent Application WO/2019/208375
Kind Code:
A1
Abstract:
Provided is a multi-axis-drive-type light deflector whereby a large drive force can be obtained. A magnetic element (7) for rotating a first frame (5) and a magnetic element (8) for rotating a reflecting plate (2) are disposed so as to be separated from each other, and a magnetic field generated by a first magnetic actuator (9) for acting on the first magnetic element (7) and a magnetic field generated by a second magnetic actuator (10) for acting on the second magnetic element (8) therefore do not readily interfere with each other, and a large drive force can be obtained in an optical deflector (1A) having a first rotational axis (O1) and a second rotational axis (O2).
