Research Order #1
Phase Ha - Progress Report #2 20 December 1954
This report covers the period from September 30, 1954 to December 15, 1954?
OBJECTIVE:
To design and construct two complete sets of equipment (4 units) to serve as
design approval models, based upon the results of the work accomplished in Phase I.
GENERAL DATA:
The design portions of the work to be performed according to Bid Proposal
No. 76-1, Phase Ha, may, as a result of the work accomplished in Phase I, be
summarized as follows:
A. Design of a suitable optical system for transmitting and receiving to
include the following:
1. A light source - thirty watt tungsten lamp as previously described
in Final Report of Study Phase I, dated 23 August 1954?
2. A reflector - 8-inch diameter (6" x 6" square aperture), 6-inch
focal length, circle of least confusion, approximately .030"
(effective) .
3. A suitable condenser lens system, using lenses of 1.5-inch aperture
and 1.5-inch focal length.
4. A mechanical modulator, as discussed in the Final Report of Study
Phase I, for modulating the light from the tungsten lamp and for
operating from the transmitter amplifier.
5. A standard "Ektron" lead sulfide cell for receiving modulated light
from the transmitter and for furnishing a signal (voice modulated)
to the receiver. The cells considered are 1 mm x 1 mum in dimension
and have a dark resistance of approximately 400,000 ohms.
Be Design of a suitable electronic system for transmitting and receiving
voice intelligence.
C. Design of a suitable power supply for the electronic system.
D. Choice of a suitable power source to furnish power to the entire system.
E. Design of a night viewer to assist in the find operation. This was
decided upon as a result of our experience in field-testing a bread-
board of the equipment and was confirmed by the opinion: of agency
personnel.
F. Design of a battery charger to be incorporated as an integral part of the
equipment. This decision resulted from discussions with agency personnel.
G. Design of Mechanical System.

CONFIDEN-I AL
At this time, the work remaining to be performed according to Bid Proposal
No. 76-1, Phase IIa may be defined as follows:
1. Completion of all the above design and layout work.
2. Construction of the first of four design approval models.
3. Test of the design approval model.
4. Construction of the remaining three of the four design approval models
and submission of the four models for evaluation.
DISCUSSION:
Optical System.
During the period from September 30th to December 15th, the design and layout
of the optical system was nearly completed. A number of parts have been purchased,
and in addition our own model shop is fabricating parts at this time. It is
expected that this work will be completed within the next two weeks.
Electronic System and Night Viewer.
Development work on the electronic system transmitter and receiver is com-
pleted, barring unforseen complications. Layout work on the electronic system
has been completed but requires some changes due to developmental modifications.
Progress is considered fairly satisfactory and the transmitter-receiver system
should be in final form by January 1, 1955.
Practically all developmental work has been completed on the following, and
design and layout work is in progress.
1. Vibrator power supply for the transmitter and the amplifier.
2. The battery charger and regulator.
3. Night viewer power supply.
However, further work is required on the Night Viewer, particularly in connection
with the optics. It is not expected that this unit will be completed prior to
January 15, 1955.
Mechanical System.
The design, Myout, and construction of the mechanical system is partially
completed.
Mock-ups have been made of the following:
1. Scan system
2. Tripod arrangement
3. Bellows system CONFIDENTIAL

4. R-T mirror switching system.
As a result of studying the mock ups, modifications are being made in the final
designs of the various components of the mechanical system. In addition we are
fabricating certain parts at the present time.
Construction of the case is also partially completed.
It is expected that all mechanical design and layout work will be completed
within the next ten days, and that the remainder of the parts will be fabricated
by January 5, 1955.
PROGRAM FOR NEXT INTERVAL:
It is expected that the period from now to January 10, 1955 will see the
completion and test of the first design approval model. Anticipating that this
model will be satisfactory with only minor adjustments, we plan on completing
the three additional design approval models by February 10, 1955.
