Submission + - MIT: One Step Closer to 3D Holography, Better Medical Imaging (

CanHasDIY writes: Remember that scene in Back To The Future: Part II, where Marty is 'attacked' by the holographic Jaws? Researchers at MIT's Research Laboratory of Electronics have gotten one step closer to such a technology: record-setting Optical Phase Arrays that can actively steer light, in the form of a 4,096-emitter array that fits on a single silicon chip. From TFA:

Chips that can steer beams of light could enable a wide range of applications, including cheaper, more efficient, and smaller laser rangefinders; medical-imaging devices that can be threaded through tiny blood vessels; and even holographic televisions that emit different information when seen from different viewing angles.
