A two stage image storage device comprising, from left to
right, a fiber optic faceplate 1, a transparent conductive
electrode 2, a semi~transparent photoconductor 3, a memory
liquid crystalline composition 4, a transparent conductive
electrode 5, a fiber optic faceplate 6, a transparent
conductive electrode 7, an optical grating 8, a photo-~
conductor 9, a defo~niable elastomeric composition 10 and
a deformable conductive minor 11,

The memory liquid crystalline composition is im3ged by
inputting an optical image into fiber optic plate 1 during
application of an electrical bias between electrodes 2 and
5, Typical memory liquid crystalline compositions include
mixtures of cholesterics and nematics and mixtures of
nematics and non~mesomorphic optically active materials,
The electro-optic effect employed can include light scatter-
ing, transmittance alteration such as with a pleochroic dye
guest in a liquid crystal host composition, optical acti-
vity changes, or diffraction such as by the variable grating
mode operation of liquid crystalline compositions.

The function of the liquid crystalline composition 5 is to
store an image that will be relayed, when needed, to the
remaining elements for deformation of elastomer 10 and
flexible minor 11 in imagewise configurations
