Abstract

A preferred structure of a new family of photoconductor-controlled, real-time light valves for use in visible conver-sion of X-rays on a real-time basis is disclosed. The basic structure of the photoconductor-controlled, real-time light valves and a detailed description of fabrication and usage is described in U.S. Patent 4,037,932 by Werner E. L. Haas and Gary A. Dir.

A preferred structure of a new family of photoconductor-
controlled, real-time light valves for use in visible conver-
sion of X-rays on a real-time basis is disclosed.

The basic structure of the photoconductor-controlled, real-
time light valves and a detailed description of fabrication
and usage is described in U.S. Patent 4,037,932 by Werner E.
L. Haas and Gary A. Dir.

A preferred structure for use in X-ray to visible conversion
is schematically illustrated in Figure 1. Layer 1 comprises a
transparent substrate such as, for example, glass. Layer 2
comprises a conductive coating of substrate 1 such as, for
example, indium oxide. Layer 3 comprises a material suitable
for any desired alignment of the electro-optic medium in layer
4 and can also comprise material suitable for the extension of
the electro-optical lifetime of the material in layer 4.
Silicone oxide or silicone dioxide film is a typically suit-
able material for layer 3. The electro-optic medium in layer
4 may comprise a liquid crystalline material, a ferro-electric
single crystal or ferro-electric ceramic or the like. Layer
5 performs the same function as layer 3 and can comprise the
same material. Layer 6 denotes a dielectric mirror can be
inserted to enhance the reflectivity of the electro-optic
photoconductor interface, thus relieving the requirement for
