Appeal No. 95-3854
Application 07/976,162
The disclosed invention relates to a method and apparatus
for projecting a three-dimensional master pattern onto at least
one exposure surface of a three-dimensional image space. An
illuminator illuminates the three-dimensional master pattern, and
the image thereon is imaged onto the surface of the three-
dimensional image space via an afocal lens system.
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. An imaging system including an illumination means for
projecting a focused image on at least one exposure surface of a
three-dimensional image space, comprising:
a) a three-dimensional master pattern bearing a desired
pattern on at least one surface thereof;
b) an afocal lens system; and wherein,
c) said three-dimensional master pattern, said afocal lens
system, said image space, and said illumination means are
relatively disposed such that said desired image is projected
onto said exposure surface.
