Abstract

There is described a deformation imaging system including an imaging member comprising a layer of a surface deformable material, a layer of an elastomer material and means for establishing an imagewise electrical field across at least the surface deformable material layer and/or the elastomer layer. Generally, the imaging members are imaged by es- tablishing an imagewise electrical field across the surface deformable material layer and/or the elastomer layer, softening the surface deformable material, such as by ohmic heating, until it deforms and subsequently allowing the surface deformable material to cool whereby the surface de- formable material layer and the elastomer layer permanently deform in an imagewise pattern corresponding to the image- wise electrical field. The imaged member may be read out with transmission or reflection optical systems employing a Schlieren optical system, The imaging mertiber may be used in a recyclible mode by erasing the image by softening the surface deformable material until it forms a smooth layer and then re-imaging the member.

FIG. 2

There is described a deformation imaging system including an
imaging member comprising a layer of a surface deformable
material, a layer of an elastomer material and means for
establishing an imagewise electrical field across at least
the surface deformable material layer and/or the elastomer
layer. Generally, the imaging members are imaged by es-
tablishing an imagewise electrical field across the surface
deformable material layer and/or the elastomer layer,
softening the surface deformable material, such as by ohmic
heating, until it deforms and subsequently allowing the
surface deformable material to cool whereby the surface de-
formable material layer and the elastomer layer permanently
deform in an imagewise pattern corresponding to the image-
wise electrical field. The imaged member may be read out
with transmission or reflection optical systems employing
a Schlieren optical system, The imaging mertiber may be used
in a recyclible mode by erasing the image by softening the
surface deformable material until it forms a smooth layer
and then re-imaging the member.

In Figure 1 there is shown an embodiment wherein the surface
deformable material layer and the elastomer layer are sepa-
rated from each other, Referring to Figure 1 there is seen
substantially transparent substrate 12 and substantially
transparent conductive layer 14 which together comprise a
first electrode, Overlying conductive layer 14 is photo-
conductive insulating layer 16 which in turn carries surface
deformable material layer 18.

IMAGING SYSTEM (Cont~d)

Layer 18 may comprise an electrically insulating thermo-
plastic resin, a wax, an epoxy resin, a thermosetting resin
or the like, Of course, where a thermosetting resin is used
the member will form a permanent image, Overlying layer 18
is thin flexible conductive metallic layer 20 which serves
as a second electrode for the member, Metallic layer 20 may
be formed by various techniques such as vacuum evaporation
and may comprise any suitable metal, Preferred compositions
for layer 20 comprise gold-indium; chrome-silver; and
titanium-silver, Overlying layer 20 is deformable elastomer
layer 22 which has arranged over it optional window layer 24
which is preferred, The electrodes are connected to poten-
tial source 26 which may be A,C,, D,C, or a combination
thereof,

In operation of member 10 an electrical field is established
across layers 16 and 18 by applying a potential from source
26 to the electrodes, With the field on the member is ex-
posed to an imagewise pattern of activating electromagnetic
radiation, The mechanical force of the electrical field
will cause the surface deformable material to deform with
accompanying deformation of...
