Ostendo Quantum Photonic Imager Hologram Projector
A tiny projector can create real 3D images that seem to float in the air. The Ostendo Quantum Photonic Imager device uses six projectors that layer light, powered by the chip which controls the color, brightness and angle of each beam of light.
(A single Ostendo Quantum Photonic Imager device)
Ostendo Technologies Inc. has spent the past nine years quietly working on miniature projectors designed to emit crisp videos and glasses-free 3-D images...During a recent test reviewed by The Wall Street Journal, Ostendo showed a working prototype: a set of six chips laid together that beamed a 3-D image of green dice spinning in the air. The image and motion appeared consistent, irrespective of the position of the viewer.
According to Ramesh Raskar, an associate professor at the Massachusetts Institute of Technology, who is working on 3-D displays for MIT's Media Lab, Ostendo's advantage and the key to its 3-D capability is its resolution. The Retina display on Apple Inc.'s iPhone, for example, has about 300 dots per inch, Ostendo's chips are at about 5,000 dots per inch.
Ostendo, which says it has several opportunities with major handset manufacturers, expects the first 2-D projector unit to be in the hands of consumers before the summer of 2015. With a lens attached, it will be less than 0.5 cubic centimeters, roughly the size of the camera in the iPhone. It also expects to begin manufacturing the second version of the chip, with 3-D capability, in the second half of 2015. The cost to the consumer should be about $30 a chip, Ostendo estimates.
Everyone who watched the original Star Wars film remembers this famous fictional hologram projected by R2D2.
(Help me, Obiwan Kenobi - you're my only hope)
Fans of Philip K. Dick recall the holo-cube display, which created a realistic image you could walk into and examine.
I think the earliest description of this idea is the telestereo from Edmond Hamilton's stirring 1928 novel Crashing Suns.
Instantly there appeared standing upon the disk, the image of a man in the blue and white robe of the Supreme Council, a lifesize and moving and stereoscopically perfect image, flashed across the void of space to my apparatus by means of etheric vibrations...
