Appeal 2007-1064
Application 10/059,242
reference beam having a substantially uniform intensity profile on a region
of the holographic recording medium. An understanding of the invention
can be derived from a reading of exemplary independent claim 1, which is
reproduced as follows:
1. A method for apodizing an incident reference beam for a
holographic recording medium, comprising impinging the incident
reference beam on an apodizer and producing a modulated reference
beam having a substantially uniform intensity profile on a region of
the holographic recording medium, wherein the modulated reference
beam is off-axis from normal at a point in the region, the modulated
reference beam is converging or diverging at a point in the region and
further wherein the region comprises an overlap of the modulated
reference beam and an object beam.
The Examiner relies on the following prior art references:
Cowan US 4,469,407 Sep. 4, 1984

The rejections as presented by the Examiner are as follows:
1. Claims 1, 3-8, and 13-16 stand rejected under 35 U.S.C. § 103(a)
as being unpatentable over Chern and Cowan.
2. Claims 10-12 stand rejected under 35 U.S.C. § 103(a) as being
unpatentable over Chern and Cowan and further in view of Dhar.
3. Claims 9 and 17 stand rejected under 35 U.S.C. § 103(a) as being
unpatentable over Chern and Cowan and further in view of Hoffnagle or
Kathman.
