Hologram Generator on a Chip

BoingBoing reader Roland Piquepaille

In "Chip Miniaturizes Holography," Technology Review says that Japanese researchers have developed a hologram generator on a single circuit board. The electroholographic system consists of a special-purpose computational chip and a high-resolution, reflective mode, liquid-crystal display panel as a spatial light modulator. With this system, they were able to generate an hologram at a resolution of 800x600 in half a second for an object of 1,000 points. Their solution is scalable in two ways: the computation is done in parallel streams, and several chips can work on a single hologram. The researchers think that there will be real-time 3D applications for television or medical imaging within five to ten years. This overview includes other details and references, including a diagram and a photograph of the hologram generator.
