I just recently heard about a company building automotive headlights with, let's say "selective lighting", using micro-mirrors. I was then surprised to find out micro-mirror devices have been available for quite a long time. [1] I wonder how come they haven't been used for a solid state LIDAR yet, they seem to be _very_ well suited for this. Are there any limitations because of the power of the LIDAR?
