Research Order #1 29 June 1954
Phase I - Progress Report #7
To study and evaluate the factors and components
involved in the design of a portable infrared communicator.
The work to be performed according to Bid Proposal
#76-1, Phase I, may be summarized as follows:
A. Evaluation of sources and sensitive elements
B. Determination of beam width requirements and
evaluation of "find-operate" systems
C. Study of modulation methods and attendant optical
systems
D. Evaluation of power sources
E. Study of required circuit characteristics
F. Manpower schedule report
The results of these studies will be used as the basis
for recommending a system to be developed.
In the June progress report it was stated that we plan
to use the lead sulfide cell as the detector in the system. A lead
sulfide cell, manufactured by Eastman Kodak Company was used

Phase I - Progress Report #7
in our experimental work which involved the study of modulating
a xenon arc by electronic means and determing the range of a
system set up in the laboratory. A.
The cell used has a dark resistance of approximately
0.4 megohms, an area of one square millimeter and a time constant
of 200 microseconds. It was not possible to select a cell for
optimum conditions since work has not progressed sufficiently far
on the electronics system and the optical system. Nevertheless,
the cell of one square millimeter gave quite satisfactory performance
in operation as the receiver for a modulated xenon source.
As previously indicated the source used in our work
is a xenon arc lamp. This lamp is type No. 2-C-1 manufactured
by Hanovia Chemical and Manufacturing Company. The voltage for
sustained operation is 25 volts d. c. at a current of 1. 2 amperes.
Complete details on the spectral energy distribution and radiation
data are not yet in our possession. However, from Hanovia and
ERDL information the lamp has a very high brightness and radiates
high intensity infrared in the region of 1. 1 microns. This radiation
is superimposed over a radiation curve of approximate black body
form.
B. Determination of beam width requirements and
evaluation of "find- operate" systems
An optical system having a beam width of 30 was used
in our experimental system to transmit light from the modulated
xenon source.
It was decided to suspend further efforts on the "find-
operate" system until more work had been accomplished on modulating
systems. Consequently, there was no experimental work done on
the "find-operate" system during the month of June.
Preliminary calculations indicate a find time not exceeding
12 minutes at a range of six miles and a beam width of 20.

Arbitrary positional accuracies 'were chosen as follows:
Horizontal + 50
Vertical + 20
It is expected that upon completion of our laboratory investigation
we can verify both our calculations and experimental work by field
observations. These field measurements are now scheduled for
the end of July.
C. Study of modulation methods and attendant optical systems
A considerable amount of effort was put in on both
theoretical and laboratory work in the evaluation of the modulated
xenon arc for this application. Use of the xenon arc presents us
with numerous problems in our application. The problems include
the following:
1.
2.
3.
Power requirements
Starting the arc discharge
Physical size and weight
Experimental work indicates 70 w. of required power for successfully
operating a 35 w. xenon lamp. This includes losses in the d. c.
supply and the ballast resistor.
The arc has been successfully established by means of
an r. f. coil (Tesla coil) with its electrode placed near the positive
electrode of the xenon lamp. Although this is probably the most
effective way for us to start this arc discharge, it is not entirely
positive and some trouble can be anticipated starting this sort of
device.
Work has not progressed far enough to establish definitely
the minimum size and weight of the equipment needed to modulate the
xenon lamp. However, since we are operating from an 800 cycle
power source, it appears that the unit may not exceed size and
weight requirements.

Phase I - Progress Report #7
Current modulation of the lamp is limited to 75%
modulation maximum, and this value varies from lamp to lamp.
Some lamps are extinguished at 75% modulation.
Using very simple optics of only 4" aperture and a lead
sulfide cell of the type previously described in this report, in 4"
optics also, for a receiver, the xenon lamp modulated at 75% gave
an average clear weather range of approximately 5 miles as simulated
on the vacuum range system in the laboratory. Further work is
proceeding on range measurements at the present time.
Based on previous calculations and design considerations
for a system using a mechanical modulator, we have placed orders
for two special galvanometers. These are modified series 101
galvanometers manufactured by Midwestern Geophysical Laboratories.
The following modifications are to be incorporated:
1.
Mirror size: 0.029" x 0. 187
2.
Ang. deflection: 16?
3.
Response: 3000 cycles - sec. - flat response
(+ 5% at
3000 cycles)
4.
Power consumption:
5 watts maximum
Midwestern Geophysical Laboratories have further
agreed to determine the feasibility of furnishing us a galvanometer
with a somewhat larger mirror, having the same performance
characteristics as the above galvanometer.
Evaluation of the mechanical system will proceed using
a tungsten source just as soon as we receive the galvanometers.
11
D. Evaluation of power sources
The problem of power sources was completely reviewed.
Information is that kerosene will be available to operate a small
internal combustion engine. This will necessitate a special engine
which can be built at a cost of $5, 000. We are awaiting a manufacturer's
written proposal at this time.

Given further consideration were the small steam engine
and turbine. The steam engine was ruled out after preliminary cal-
culations indicated the requirement of too much water. Weight factor
alone ruled out a small turbine.
The small gasoline engine has been satisfactorily muffled
as far as exhaust is concerned. However, further muffling is required
on the intake system, and shog*Cmounting and acoustic shielding will
be required around the engine itself.
We feel that the problem of the power source has been
resolved to the extent that we can successfully use this small engine
and meet operating power and noise requirements.
E. Study of required circuit characteristics
This system will either be a linear modulating system,
such as the current modulator used in the experimental work in
modulating the xenon arc, or the infinite clipping circuit previously
mentioned.
F. (See Manpower Schedule Report attached)
PROGRAM FOR NEXT INTERVAL
Either the tungsten source and mechanical modulator
or the xenon source and electronic modulator will be chosen during
this period of time. This decision will very nearly dictate the
electronic system.
Problems regarding beam-width and find-operate will
be pursued along with work on the optical system.
Feasibility of using transistors in the electronic system

will be given consideration, and a decision reached as to whether
they will be used in place of vacuum tubes.
A proposal will be submitted for the system to be developed.
The proposal will review system requirements and describe com-
ponents selected, giving reasons for the selection of the following:
1. source (radiation)
2. receiver (detector)
3. optical system
4. modulating system
5. electronics system
6. power source
Principles of the proposed system will be discussed, outlining
expected system performance.
Pertinent data, calculations, sketches, circuit diagrams
accumulated in the study phase will be attached to the appendix of
the final study phase report.

MANPOWER SCHEDULE REPORT
As originally prepared for our proposal #76-1, our
schedule called for 6 months for Study Phase I, 6 months to produce
two design approval models in Phase Ha, and 4 more months to
produce 20 developmental models in Phase IIb. It is now under-
stood that the Study Phase I is to be completed 31 July 1954. With
5 months assigned to Phase IIa and 4 months to Phase IIb, the
entire contract would then be completed by 30 April 1955. Our
Contracts Administrator, is requesting extension
of the contract to that date.

cleared. Three model shop personnel were also made available
to this project by clearance in April, and in June and
were also cleared for this project. Thus the Phase I
schedule will be completed with only about 45% of originally scheduled
manmonths applied to this phase, although 72% of the scheduled
electrical engineering manmonths were used.
Following the Phase I schedule is a detailed manpower
assignment for the month of July. It is to be noted that our plant
will be shut down for the first two weeks of July for our annual
vacation period.

Finally, the following chart compares the original schedule in man
months with that which has been used and is now scheduled for the balance
of the contract. It is to be noted that while less man months were used
in Phase I than originally planned it is now contemplated that more man
months will be applied to Phases IIa and IIb to make up for this deficiency
and that the total number of man months applied will be as originally
scheduled. It is hoped that the new schedule can now be adhered to with
reasonable accuracy.
