A new take on 3D volumetric display
And here’s the explanation of what you’re looking at: “Light from a source (1) is reflected by a polarizing beamsplitter (2) towards a spatial light modulator (3), whose image patterns are generated by a personal computer (4). Projection optics (5) make image patterns onto a rotating double helix screen (6).”
But is this just theory turned into prototype for proof of concept, or is this something that might soon be commercially available? SPAR called Geng to find out.
Partly, this is because Geng, who has received government grants over the years to work on everything from an ultra-miniature lidar device to a 360-degree video surveillance camera, sees the display as only part of an overarching capture-process-display system.
