Yup, flash lidar has some ways to go before it can become usable, in my opinion. I don't think there's much hope. I shouldn't say more! Instead of using the time to determine the distance as typical lidar does, it uses the phase difference, and requires a precise phase measurement. This unfortunately is not nearly as accurate, especially with such a low-powered laser.

> Instead of using the time to determine the distance as typical lidar does, it uses the phase difference, and requires a precise phase measurement. This unfortunately is not nearly as accurate, especially with such a low-powered laser. To be honest, I'm a little curious about this because it seems exactly the opposite to me. In my experience, area scanners use phase shift methods to measure, but I know there's a lot of variety out there that I'm not exposed to. Low-powered lasers would, I expect, limit working distance--but I'm a little surprised to find it would have significant impacts on the measurement method.
