Això diuen, que podrem portar a la butxaca un projector pel nostre
mòbil, portàtil, etc. la idea del projector no és com la
coneixem ara, però el resultat final si, si voleu saber com
funciona:
Key to the device’s diminutive size is the lack of lenses and high-power
light bulbs. Conventional digital video projectors form images by generating a
small picture on a transparent microdisplay inside the projector, then shining
a high-power light through the microdisplay to a large magnifying
lens.
In the researchers’ design, a two-dimensional hologram is shown on the
microdisplay rather than an image, and the projected image is formed by shining
a laser beam through the microdisplay, which scatters the light into a
particular pattern. “No lenses are required — the projected image is formed
entirely by diffraction,” said Adrian Cable, a researcher at the University of
Cambridge in England.
