Abstract

A lenticular lens panel placed against the read-in side of a RtJTICON imaging member and a coarse diffraction grating placed at the read-in aperture avoid the need for an expensive and difficult-to-manfacture fine diffraction grating on the RUTICON member.

A lenticular lens panel placed against the read-in side
of a RtJTICON imaging member and a coarse diffraction grating
placed at the read-in aperture avoid the need for an
expensive and difficult-to-manfacture fine diffraction
grating on the RUTICON member.

The RUTICON device comprises conductive layer 2, photo-
conductive layer 6 and elastomer layer 7 with mirrored
surface 8 on transparent support member 3. Conductive
transparent layer 2 and mirrored surface 8 are connected
by D.C. power source 10. Previously known such RtJTICON
devices also include a fine diffraction grating between
conductive layer 2 and photoconductive layer 6. optical
images striking photoconductive layer 6 result in a
corresponding imagewise increase in the field across
elastomer layer 7 and deformation or wrinkling of mirrored
surface B in imagewise configuration. The wrinkling or
deformation in the imagewise area of mirrored surface 8
corresponds to the fine diffraction grating in previously
known RUTICON devices.

In the arrangement pictured above, object 1 is imaged onto
photoconductive layer 6 through coarse diffraction grating
11 positioned approximately at the aperture of read-in
lens 4 and lenticular lens panel 5. The lenticular lens
panel has the effect of optically reducing the size of the
coarse diffraction grating so that it is in effect a fine
diffraction grating at the...
