For invisibility to work like that for more than one viewing angle you would need to add the initial number of pixels for each angle you want to support. So it’s unlikely to work even at small sizes. So 10 angles, you’d need 10x the original number of pixels.
- nine_k 5y agoThis works for very narrow FOVs, though. E.g. a stealth aircraft can absorb the radar signal, analyze its direction (using a phased antenna array) and send back a "reflection from earth" with a proper delay. This renders the aircraft effectively invisible to the radar, provided that the covering of the aircraft indeed does not reflect much back.
- fingerlocks 5y agoWith facial detection and one observer, we could orient our projection as the viewing angle changes. It wouldn’t be true invisibility, but maybe at best a Predator-style fuzzy cloak?
