(Theoretical Investigations)
1. Introduction
In addition to the planned literature and patent search which was
required during the first phase of three months, some preliminary
measurements on CGW materials showed their definite applicability
for rear view screens if certain modifications are made. These
results, together with the theoretical information acquired during
the first phase, enable us now to concentrate our theoretical in-
vestigations only on these parameters which are important to evaluate
the various types of material. The second phase of this program will
also include the preparation of some instrumentation set ups and
preliminary experimental work on selected materials. A .more detailed
outlined is given in the following paragraphs.
II. Theoretical
A. Scattering
Because of the importance of the scattering distribution and its
dependence upon particle size, scattering theory will be employed
to specify the size of scattering centers in preliminary rear
projection screen materials.
B. Resolution
This will be an analytical study of physical factors, such as
particle size, screen thickness, scattering characteristics, etc.,
which degrade resolution.

performance, we will investigate the sensitivity of different`
projection systems to changes in system parameters, such as
ambient light, screen gain, bend angles, projection distances, etc.
III. Instrumentation
Instrumentation will be designed and constructed to measure the
following parameters:
1. The angular scattering distribution.
2. The modulation transfer function which is a measure of
the resolution of the screen.
3. The color characteristics of the screen.
IV. Materials Investigations
We will continue investigating CGW materials and working with our
materials groups towards specifying requirements for preliminary
samples of rear projection screen materials which have been discussed
in Technical Report'Section IV, concluding Phase I of the program.
