Appeal No. 1998-0818
Application No. 08/319,143
The invention relates to recovering a distorted optical
image. On page 2 of the specification, Appellants identify
that the method of recovering the optical image involves
optically performing a pseudo deconvolution of the image. The
device to perform the optical pseudo deconvolution of the
image is shown in Appellants’ figure 4, and described in the
specification on pages 8 through 11. On page 8 of the
specification, Appellants identify that the distorted or
blurred image is captured by a vidicon and the image is
inserted into a Spatial Light Modulator (SLM). On page 9 of
the specification, Appellants describe how a Fourier transform
image is created by illuminating the image on the SLM with a
laser. The image then passes through a lens,
item 30, to create a Fourier transform of the blurred image.
The Fourier transform image is acted on by two computer
generated optical filters, items 22 and 22', to create a
filtered image. One of the filters is a phase encoded filter
and the other is an amplitude encoded filter. On page 10 of
the specification, Appellants identify that the filtered image
is projected on an output plane through a second lens, item
36, which performs a Fourier transform on the filtered image.
