Title:
LIGHT SOURCE DEVICE AND SENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/185367
Kind Code:
A1
Abstract:
A first drive unit (220) rotates a first optical member (210) about a first virtual axis (A1), and a first element (200) thereby causes light emitted from a light source (100) to rotate about the first virtual axis (A1) in a state of being inclined with respect to the first virtual axis (A1). A second drive unit (320) rotates a second optical member (310) about the first virtual axis (A1), and a second element (300) thereby causes at least a portion of the light rotated by the first element (200) to be radiated to the periphery of the first virtual axis (A1) in a direction intersecting a Z-direction.
