OPTICAL CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/193466
Kind Code:
A1
Abstract:
An optical control system (10) comprises an optical reflector element (100) and a control device (20). The optical reflector element (100) comprises a reflective body (110), and a first swinging part (210) and second swinging part (220) disposed at positions sandwiching the reflective body. When the first swinging part (210) and second swinging part (220) are swung so as to rotate in the same direction around a first axis, the control device (20) causes each of a first actuator (214) and a second actuator (215) of the first swinging part to vibrate so as to respectively generate, in the first actuator (214) and the second actuator (215), a first location and a second location having opposite directions of vibration in the through-thickness direction, and causes a first actuator (224) and a second actuator (225) of the second swinging part (220) to vibrate so as to respectively generate, in the first actuator (224) and the second actuator (225), a third location and a fourth location having opposite directions of vibration in the through-thickness direction.
