Appeal No. 1997-3969
Application No. 08/175,052
providing a plate and defining a working area on the
plate having an area at least equal to a sum of required areas
for all of the subapertures for receiving computer generated
holograms consisting of the plurality of side-by-side
subapertures;
dividing the working area into contiguous polygonal
subapertures, each subaperture having the required area for
producing a working image, the contiguous polygonal
subapertures having boundaries which are either common
boundaries with adjacent polygons or boundaries of the working
area on the plate, whereby all subapertures in the working
area are continuously tiled and adjacent to other subapertures
forming an uninterrupted continuum over the working area of
the plate; and,
producing a computer generated hologram by placing
optical features on each subaperture to produce the working
image from each subaperture.
The examiner relies on the following references:
Hirsch et al. (Hirsch) 3,619,022 Nov. 09, 1971
Akkapeddi et al. (Akkapeddi) 4,897,325 Jan. 30, 1990
Haines 5,194,971 Mar. 16, 1993
The following rejections are before us on this appeal:
1. Claim 1 stands rejected under 35 U.S.C. § 103 as
being unpatentable over the teachings of Akkapeddi in view of
Haines.
2. Claims 2-7 and 18-25 stand rejected under 35 U.S.C.
