Pocket projectors

By at 8:28 am Thursday, Nov 4

The New York Times has an interesting article about pocket-size digital projectors that could someday attach to cell phones or laptops. As with most mobile technology, the problem is power. Still, several prototypes have been developed.
Lasers rather than L.E.D.'s are the basis for a hand-held projector in development at Light Blue Optics, a company in Cambridge, England. "We want a device that you can download films to, press a button and see a huge screen projection," said Adrian Cable, director of the company.

The large projections are produced holographically. "These are not the three-dimensional holographic projections of Princess Leia in 'Star Wars,' " Dr. Cable said, but instead two-dimensional ones produced by an optical process different from standard projection.
