Application No. 08/319,143
uses an amplitude encoded 3 filter and a phase encoded filter
in a Fourier transform plane. We find that Chen teaches that
the phase encoded filter is iteratively adjusted. See column
9, lines 5 to 15. We find that iterative adjustment of the
phase encoded filter does not meet the definition of either a
binary phase coded filter, a ternary coded filter or an
amplitude coded filter. Further, we find that Chen teaches
that the filters are adjusted on a pixel-by-pixel basis.
Column 5, lines 40 through 46. Thus, we find that Chen does
not teach that the amplitude encoded filter has a
transmissivity which increases along radial lines extending
from a central portion of said amplitude. Accordingly, we
will not sustain the rejection of claims 3, 4, 6, 7, 11, 12
and 14 under 35 U.S.C. § 103.
