has someone explored what the state of the art is if you just use two 1080p LG laser projectors and 2+ cameras and clever software

it's 1080p of resolution in lighting from two angles at 60 fps for like ~100-200 W. if you had some good cameras and some clever and fast software you could use this thing to illuminate anything you need to know about -- a high frequency light probe. i don't think you need coherent light at all or phase control, you'd just like timing control so you can strobe between left and right lights and use the variation to better characterize objects.

whole system seems doable in budgets of ~$8k hardware (total guess...)
