A. Current Status of Work
The following areas have been worked on during this period.
1. The influence of limiting the target to 15 bars was
further investigated. The full mathematical details
will be given when we have more examples worked out.
We have not been able to get the results in a closed
form, but for any given transfer tunction we can com-
pute the influence. For representative transfer func-
tions computed to date the influence is negligible.
Again, when we finish our exampleSwe will give a full
report.
2. The technique to align the polarizers is fully worked
out and is satisfactory.
3. The modulation of the filters, up to this point, were
measured on a regular microdensitometer. These instru-
ments use a large cone of light which comes from the
filter. The way we use the filters is with a fairly

small cone of light. The densities measured in these
two ways might lead to different results due to the
"Callier" effect. To ensure that the modulation
measured on the filters is the one that is effective
in the use of the instrument, we are building equipment
to measure the filter under conditions of actual use.
This equipment will be ready in about two weeks.
4. The eyepiece filter-holder has been redesigned to its
final form and one unit should be ready in about two
weeks.
5. The target-holder and light box is on the drafting board
for final design. It should be ready for the shop in
approximately one week.
B. Problem Areas Encountered
No problem areas were encountered during this period.
C. Projected Work for Next Monthly Period
1. Work will continue in the areas described in Section a.l.
a.3, a.4 and a.5.
2. Work will commence in two weeks on the second model.
