Appeal No. 1996-3284
Application 08/154,864
The invention is related to an apparatus and a method for
enabling a viewer to perceive a 3D image from a projection
panel. The screen of the invention is a 2D array of scanning
lasers or other collimated light sources that serve as active
light sources. In the preferred embodiment, each laser
produces a pencil-like beam that is raster-scanned across the
viewing auditorium. Each eye in the auditorium is illuminated
with light from a given point on the screen for only a brief
instant, as the laser’s beam scans across that eye in its
raster-scanning of the entire viewing auditorium. The eye
integrates these momentary flashes of light from different
points on the screen (i.e., from all of the hundreds or
thousands of lasers comprising the screen) to produce an
image. The invention is further illustrated by the following
claim. Representative claim 3 is reproduced as follows:
3. An apparatus for projecting a 3-dimensional image
into a viewing space, the apparatus comprising:
a 2-dimensional array of light producing elements;
means for modulating the light produced by the light
producing elements;
directed to the specification and the drawings only.
