Appeal No. 2001-1208
Application No. 09/057,585
The disclosed invention relates to optics for a reflection-
type projector.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. A reflection type projector comprising:
a light source for emitting an input light;
only one image forming unit having a plurality of pixels in
a two-dimensional array structure, each of the plurality of
pixels being independently driven, for forming and reflecting an
image from the input light;
a critical angle prism having a transmission/reflection
surface disposed along an optical path of the input light, the
transmission/reflection surface transmitting the input light from
the light source to the image forming unit, and reflecting light
that re-enters the critical angle prism from the image forming
unit; and
a projection lens unit for enlarging and transmitting the
light reflected from the transmission/reflection surface of the
critical angle prism.
