a. Current Status of Work
The following areas have been worked on during the
period starting April 24, 1965.
1. Target fabrication. The equipment to produce the
final targets have been designed and built. The
fabrication of the target has been started.
2. During this. reporting period we received a complete
set of filters. The-first set is mounted in the
holders and we have begun our evaluation to de-
termine the best contrast values for these filters.
3. The additive method, as described in Report No. 3,'
was.more fully studied. Our conclusion is that,
for the purpose of checking viewers, this method is
preferable. There is no need to change the input
platen of the equipment, and the precision obtainable
is about the same as in the originally-proposed
method. The best way to implement this method seems to
be to use targets with a visibility VT = Vo = 1.
