We have seen the future of television, and it’s holographic. Researchers at MIT’s Media Lab have developed a new projector based on the principles of guided wave optics to construct the spatial light modulator (SLM) that is the heart of digital holography. Gizmag reports that the “MIT holographic projector, which contains an SLM costing US$10 to fabricate, provides 3D images at 30 frames per second (fps) with a resolution similar to that of a standard-definition TV.” Continue reading for a video and more information.
The MIT group has demonstrated a holographic display that can display 3D images with a resolution of about 400 x 400 x 138 pixels at five frames per second, as seen in the initial picture above. They are presently making a prototype with 1,250 channels (leaky-wave waveguides), with which they expect to achieve a bandwidth of 125 Gigapixels/sec, generating an image of a cube about 1,500 pixels on a side.
