Status Report
Coherent Enlarger Evaluation Program, Support Activities
STAT
STAT
STAT
Our participation in the program began during the week of 8 November 1965.
During this week, the enlarger was shipped STAT
assembled and put into operating order. The laser was cleaned and satis-
factory output was measured. Enlargements of resolution targets were made
in order to determine the proper position of the focal plane. Finally,
operating procedures were briefly demonstrated to personnel. STAT
In general, the above installation went very smoothly. Tech-
nicians began making the permanent service connections even before the
enlarger was completely assembled.

On the 18th of November, a return visit was madel STAT
During the week that had passed had not done STAT
any experiments but had completed the installation o services and had begun STAT
analytical computations.
STAT
The next visit was made on 19 January 1966 STAT
personnel displayed enlargements ot three-bar
targets which we Mae on e enlarger (on 12 November 1965) and which STAT
made. It was said that these enlargements showed that the optical system STAT
was not at;optimum alignment. It was also said by personnel that the STAT
enlarger required adjustment as regards light leaks, 92" roll film feed,
vapor removal and vacuum pump vibration. All of the above points were agreed
upon by all present. We will make these adjustments before 11 February.
Apart from adjustments, the personnel commented that exposures could STAT
be shortened if a more powerful laser were employed (see enclosure). In
addition, there were discussions of double-slit and edge gradient methods of
determining the degree of coherence at the object plane; no other experi-
mental results were shown, no other experimental or anlytical work was STAT
discussed ~y~personnel.
CONCLUSIONS: In general, the meeting of 19 January 1966 was not encouraging
to us. We have a contract to participate in the evaluation program and have
extensive capabilities in physical optics. Funds, personnel and facilities
are available to make calculations, perform experiments or supply materials;
thus, the evaluation program might be accelerated if ould seek STAT
closer co-operation with us. We recommend that progress review meetings be
scheduled at two week intervals so that all concerned may be most completely
informed. STAT
