#2Very cool tech, and as a fan of Hyperion I think the company name is very cool as well.

#3> The OS0 lidar sensor: an ultra-wide field of view sensor with 128 lines of resolution
> The OS2 lidar sensor: a long-range sensor with up to 128 lines of resolution
> Two new 32 channel sensors: both an OS0 and OS2 version
> Price: Starts at $16,000 with volume discounts available
I would LOVE to get my hands on this tech. Maybe in 5-10 years when the price comes down to commodity level for hackers to play around with. :-)
Since LIDARs impact airflow over the top of a car, is there a way to make LIDARs less spherical and more triangular or elliptical? How would that impact the scans and can that impact be corrected/recalibrated mathematically?

#4I wonder how well this works if 20 such devices shine on the same object.

That's sort of like asking how well cameras would work if 20 of them were looking at the same object.
Lidar sensors can interfere with each other, and a certain industry-standard company is famous for having terrible problems with this issue, but there are engineering solutions to this problem. FMCW is a popular choice, and gives the benefit of providing instantaneous velocity readings. Of course, due to the Heisenberg uncertainty principle, this means you also get worse distance estimation. There are other ways to engineer around the interference problem as well.

While this is a ~80% discount on other 128 beam sensors, it's unfortunately still out of reach for the hacker community. We absolutely plan to get prices down to an affordable level for individuals in well under 5 years!
Also, Ouster runs a sponsorship program that gives deeply discounted or free sensors to cool projects. If you have a cool idea, shoot me an email: derek.frome at ouster dot io

Then it's not really like 20 cameras looking at the same object. Mostly due to the fact that cameras are passive observers and not really emitting much. And if they do, it's light and it won't really affect the others because they all benefit from it (within reason).
I'm reasonably certain that such issues will still appear in productive use in the future but will get fixed at the time, not in labs today.

I'd imagine that those cameras might have trouble if they were all using long exposures and strobe lights.
As someone outside of the industry, what's the company that has problems with interference?

Fair enough, I didn't really expand my comment enough to make my point and was about to delete it but now that someone replied I'll just leave it as is since I don't want to write a small essay.
A good lidar sensor won't have issues with interference.

This is very nice, if I only I had a cool project, I just have lukewarm ones!
