MIT Could Make Inexpensive 3D Holograms A Reality
Researchers at the school's Media Lab are developing a prototype color video display using an optical chip that only cost $10 to build.
Researchers at MIT’s Media Lab have reported a new approach to generating holograms that could lead to the production of inexpensive color holographic-video displays. The same approach also renders much higher resolution 2D displays with lower power consumption.
Daniel Smalley, a graduate student in the Media Lab, is using the approach to build a prototype color holographic-video display with a resolution roughly the same as a standard-definition TV, which can update video images 30 times a second (fast enough to produce the illusion of motion). At the heart of the display is an optical chip, which Smalley built using MIT facilities for around $10.
