Is anyone aware of a LIDAR solution including a horizontal angular sweep of >10 degrees and up to 10-20 meters of range?
Luminar should have the technology for that, but I'm not sure their products are even publically available anymore. I think an automobile consortium grabbed Luminar, to keep their products/technology away from the competition.
You can search for Luminar and its competitors, perhaps at self-drive conferences a few years ago.
Luminar was using arrays of photodiodes, and/or arrays of lasers, to up the scan rate and also increase the lateral pixel density.
===================================
Sounds like you want to have a BAR OF LIGHT, and have a photodetector respond to reflected photons.
