Would anyone know where to look to aquire that sort of monochrome projector? And in general how to implement a camera->projector loop with that low latency / high frame rate? I've been looking into a similar idea and have bodged together something like: USB camera -> laptop (opencv) -> consumer LED projector (via Hdmi). Probably unsurprisingly, latency is a problem.
