HIGH RESOLUTION SCREEN
The company moved to a new plant in 0 the end of
August. It does not appear that the move disrupted any
of the work on this program. The new facilities are
excellent, particularly their dark tunnel.

is phase of the work was highly successful. The only
thing left to complete is the projector and lens.
Using small 2" x 3" samples, Dick developed a rear pro-
jection screen which is transparent to visible light,
has no visible particulate structure and has a luminance
distribution which is quite close to a true Lambertian
surface; i.e., equal brightness over the full range of
viewing angles. In addition, screen resolution exceeds
100 lines per millimeter.
Small 2" screen samples were used as specified in the
contract in order to concentrate the effort on the crux
of the problem; i.e., the evaluation of a variety of
coatings in the lab. In exploratory work of this sort
it is important to identify the basic problem as was done
here, work on that and not burden the investigation with
extraneous requirements. The small 2" sample size was
well suited to the phosphor coating search. With that
success in hand, it is now important to expand the scope
of the work to produce larger screens of the three or
four phosphors of greatest interest.

says he can authorize the work immediately
it the technical monitor approves. Approval is urgent
so as not to delay the feasibility demonstration.
Even after a feasibility demonstration which success-
fully proves the technical concept there is a lot to be
done before a piece of working gear will be available
for routine operations. The work should be pushed with
all dispatch. It is particularly important to plan
ahead and overlap the administrative preparation for new
work with the final stages of current work so that there
will not be long gaps or shutdowns in the technical
effort. A good brisk pace and continuity of effort is
highly desirable. Some progress has been made in de-
fining the direction of follow-on work. Here again it
is important to go to the heart of the problem and not
burden the immediate follow-on work with premature re-
quirements. I believe the follow-on work should be:
A. Long term continuation of the phosphor search
and measurement of phosphor characteristics.
This can all be done in the lab with small
samples.
B. Fabrication of a large screen, large projector

the true applicability of the phosphor screen
