What are some of the applications of this technology?

Edit: I'm also wondering if anyone has any idea as to the estimated cost of such a technology? Thousands, tens/hundred of thousands, millions? A quick search of lidar sensors seem to be in the range of $2500 - ~$10000 for ranges of sub 30 meters.

This technology seems similar(?) to lidar from what I can tell.

Teslas have been shown to prevent accidents by braking based on things drivers can’t see. https://www.mobilescout.com/tech/news/n77946/tesla-autopilot...

I imagine that idea could be improved more with this technology, but Tesla is very anti lidar so it’s have to be someone else.

Military, police, surveillance. The usual suspects when it comes to oppressive regimes like china.

On a more upbeat note though, imagine the possibility of producing a 3d image of your internals during keyhole surgery or inspecting remote structures like solar panels and dams via satellite.

My local police department would be really interested in this tech. They've been using automated license plate readers, facial recognition tech, drones, predictive policing, and have a Ring doorbell partnership.

In a very real way, American police departments are functioning in roles that the military serves in most dystopian societies.

Where do you live? Remind me not to visit.

Any major city in the United States has all of these features

It's really incredible that we just let ourselves slide into this surveillance dystopia, isn't it? I yearn for the halcyon days of August 2001.

Dirt cheap. Laser with galvo (like many laser projectors for light shows have), plus 3 photodiode detectors and optics.

Most of the cost will be in the telescopes.

If you don't count personnel time integrating/fiddling around, maybe $1000 at qty 1?

First one that comes to mind is military. Where to aim (or not aim) your high powered weapon that can shoot through a wall.

Realistically there aren't any practical applications. It's a very cool demo though.

Seeing inside a building has no practical applications?

Or other non-line-of-sight things, like sensing through an aperture in a body?
