Abstract

A deformation imaging member comprising a deformable metal~ lic layer arranged between a pair of deformable layers at least one of which comprises an elastomer material. The imaging member may include a pair of electrodes for estab~ lishing an electrical field across the deformable layers. In one embodiment the member includes photoconductive material and is addressed optically and in another embodiment a pair of electrodes comprise an electrical X~-Ymatrix address system,

A deformation imaging member comprising a deformable metal~
lic layer arranged between a pair of deformable layers at
least one of which comprises an elastomer material. The
imaging member may include a pair of electrodes for estab~ lishing an electrical field across the deformable layers. In
one embodiment the member includes photoconductive material
and is addressed optically and in another embodiment a pair
of electrodes comprise an electrical X~-Ymatrix address
system,

In the embodiment illustrated, member 10 includes substan- tially transparent substrates 12 and substantially trans-
parent conductive layers 14 which comprise a parallel pair of electrodes. Overlying the bottom electrode is a layer of
photoconductive insulating material which in turn carries a
first deformable material layer 18. Overlying deformable layer 18 is deformable metallic layer 20 which in turn
carries a second deforinable material layer 22. The elec-
trodes are connected to potential source 25, which may be
A,C,, D.C., or a combination thereof, through leads 24, In operation, an electrical field is established between the electrodes and an imagewise pattern of activating electro- magnetic radiation, which may be spatially modulated, such as, for example, by a line grating located immediately ad-
jacent the photoconductive layer, is directed upon the
imaging member through the bottom electrode, The mechanical
force of the electrical field causes deformable layers 18
and 22 to deform at their interfaces with metallic layer 20
in a pattern corresponding to the imagewise activating radi~
ation. It should be noted that one or both of the elec-
trodes are not required when the electrical field is estab-
lished by means of corona charging. The imaged member may

be read out in reflection by a Schlieren type optical system.

DEFORMATION IMAGING MEMBER (Cont'd)

Deformable layers 18 and 22 may comprise any suitable elastomer material, dielectric liquid or dielectric gas. As
noted previously, at least one of layers 18 and 22 comprises
an elastomer material. Where the deformable layer comprises
a dielectric liquid or a dielectric gas, the liquids and
gases suitable for use typically have good electrically in-
sulating pro...
