Researchers from Cambridge and Light Blue Optics have developed a prototype pocket-sized video projector that would easily be fitted into future mobiles phones and pda’s.

The system creates a projection by displaying a hologram on the microdisplay, and the projected image is formed by shining a laser beam through the microdisplay, which scatters the light into a particular pattern.
