RESEARCH AND DEVELOPMENT
PROJECT APPROVAL REQUEST
I. Identification
A study is proposed to determine the feasibility of develop-
ing a "Light Amplifying Screen" utilizing dipolar suspension. The
ro=will be conducted with at the 25X1A
level and is programme or isca. ear under Category 2 5X1A
VI, "Other Developments". More specifically this study is compre-
hended under the subcategory titled "Optical Dipoles".
II. Objectives
The purpose of this program is to study the feasibility of
utilizing a, dipolar suspension for a high-intensity, dynamic display
of highly magnified, projected images. (The particular technique
proposed utilizes a proprietary application of optical dipoles.)
After feasibility has been established, a prototype light ampli-
fying screen will be constructed and tested. This screen may have a
direct application to present viewers.
There are many questions that must be answered before it is
possibly to say that such a device will have a direct application to
present viewing devices. The main goal of the study is to determine
the level of energy transmitted by the film that is required to con-
trol the dipole suspension. That is, with this type of system, will
less energy be required to pass through the film than with present
systems?
III. Background
Present viewing systems are limited by the amount of energy
that must pass through the imagery that is being projected onto the
screen. Since more light per unit area is needed as magnification
is increased, magnification is limited by the heat absorbed in the
emulsion. One way to overcome his limit would be to develop a
screen that would control a bright light source proportionally to a,
weak image falling on it. It is felt that the- proposal de- 25X1A
scribes a technique which could be used to develop a screen of this
type.
IV. Technical Specifications
The dipole screen is constructed so that an electric field may
be applied across the screen and the aligning dipoles allow light to
pass through the screen. If ultraviolet illumination is projected onto
the screen, the dipoles are ionized and the ions migrate to the faces

where they shield the electric field. The space thus illuminated is
free of the electric field and the dipoles in this area are returned
to random orientation by Brownian movement. This random orientation
prevents the transmission of light through the screen at this point
and this portion of the screen appears dark. Thus if one projects
a negative film on the screen, its positive will be reproduced.
An auxiliary light source, in the visible range, is flooded
on the screen, thus increasing the brightness of the image projected
by ultraviolet. Only enough energy to activate the dipoles must be
transmitted by the film. The high-intensity light that is necessary
for high-magnification is not projected through the film but from
the auxiliary source.
The purpose of this study is to determine whether this principle
offers a gain over existing systems. In order to answer the main
question, the following should first be determined:
A. What level of energy is needed to control the
dipole suspension?
B. How does the auxiliary illumination affect the
dipole suspension?
C. How much energy is lost after it is transmitted
through the film and before it causes the dipoles to
react?
D. How fast will the dipoles react after illuminated
and how fast will they return to their original state?
E. Is there any migration of the image after it has
been formed?
F. What is the quality of the image?
1. The Modulation Transfer Function.
2. The density range.
3. The density discrimination.
It is anticipated that the study proposed dill provide
the comprehensive experimental data required to answer these questions.
