What's the type of 40-beam lidar ?

Hello,
I'm very curious about the 40-beam lidar. I haven't seen 40-beam lidar before.
Can you tell us what's the type of 40-beam lidar? It's from velodyne or other companys?

No file, test, or entry point is identified in the issue. Start by locating the project’s documentation for the 40-beam lidar and verifying the sensor type and manufacturer from the available dataset or project sources. Done means the vendor and lidar type are clearly documented for users.
