Lens-less flat camera - terrafamilia - 02-16-2016 Bulky Cameras, Meet The Lens-less FlatCam Camera technology has improved dramatically in the past decades, but one thing about even the newest cameras has stayed constant: They all have lenses. Now, that's changing. Engineers in Texas are building a camera that can make a sharp image with no lens at all. A stepping stone to OPA sensors? Here's the paper - FlatCam: Thin, Bare-Sensor Cameras using Coded Aperture and Computation Ciao, Terrafamilia RE: Lens-less flat camera - Rynn - 02-16-2016 Cool. I like the idea of a wall paper that is covered in thousands of these sensors. Seems like a good basis for invisible unisurv. RE: Lens-less flat camera - stevebowers - 02-17-2016 This would be useful for chameleon tech. A flatcam layer receives the light incident on one side of an object, and a phased-array system transmits the same image on the opposite side of the object, thus making the object appear transparent in all directions (not just one). RE: Lens-less flat camera - JohnnyYesterday - 02-17-2016 You'd need phased arrays to act as the cameras and display to achieve true invisibility; the scene would have to be recorded holographically. Otherwise, what you'd have would be a flat moving image wrapped around a 3D object--which would look like Predator camo. RE: Lens-less flat camera - stevebowers - 02-17-2016 That would be better than nothing, but you are right. Invisibility is a difficult trick, and I don't expect to see it in my lifetime ![]() |
