Title:
IMAGE SENSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/028938
Kind Code:
A1
Abstract:
An image sensing device (1) comprises: an illumination device (10) including a light source that emits a light beam and an illumination optical system that scans, in a second direction (Y), a linear illumination area (13) extending linearly in a first direction (X) on a virtual reference plane (24), the linear illumination area (13) being an illumination area to which the light beam is projected, the second direction (Y) being orthogonal to the first direction (X); a camera (20) that performs an imaging operation by scanning, in the second direction (Y), a linear imaging area (23) extending linearly in the first direction (X) on the reference plane (24); and a control circuit (30) that controls the operation of the illumination device (10, 50, 60) and the imaging operation of the camera (20) so that the linear illumination area (13) and the linear imaging area (23) keep overlapping on the reference plane (24). The optical axis (11) of the illumination device (10) and the optical axis (21) of the camera (20) are non-parallel to each other, and intersect with each other on the reference plane (24).
