Title:
OPTICAL SHAPING MODULE, AND LASER RADAR DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/103814
Kind Code:
A1
Abstract:
The present application relates to the technical field of optics, and provides an optical shaping module, and a laser radar device and system. The optical shaping module is configured to compress and homogenize the beam of received incident light in a first direction; the optical shaping module is configured to be discrete components comprising a first direction compression module and a first direction homogenization module, the first direction compression module comprises at least one first direction compression lens and is configured to compress the light beam in the first direction, the first direction homogenization module comprises at least one first direction homogenization mirror and is configured to homogenize the light beam in the first direction, and the first direction compression module is located on a light exit side and/or a light incident side of the first direction homogenization module; or the optical shaping module is configured to be an integrated component, the integrated component comprises an incident surface and an exit surface, and the incident surface and/or the exit surface are/is configured to compress and homogenize the light beam in the first direction. The size of light spots on a near-field working surface is compressed, and the size of a rotating scanning mirror used in conjunction is reduced, thereby meeting the requirements of miniaturization scenarios.
