MEMO FOR RECORD
T; Change Detection Conference,
9-10 April 1963
STAT
The Change Detector program is essentially on schedule. The electronics
is a little ahead of schedule, although the shadow rejection circuitry and
the final design are a little behind schedule. This will have no effect
on final completion date, however, has obtained approval for about
$33,000 additional to amend the contract to provide for viewing with 30
lines per man. instead of 20 as prescribed in the contract. This will re-
quire a CRT with smaller spot diameter which must be obtained by special
order, more rigid frame bracing, and better voltage control. Delivery
date will be extended two months because of the time required to obtain
the new CRT.
was asked to prepare a proposal for a study on the feasi-
bility, met ho s, and costs of developing a Change Detector that will be
compatible for use with photography having the highest available resolu-
tion. will have this proposal reedy in about a month.
Several concepts of change detection muet be considered. Nigher
-
resolution might be required for interpretation and analysis than
change detection. Change detection might be done using the best available
CRT, then the scene could be magnified by some other method for viewing
ith greater resolution. Or a CRT with higher resolution might be developed.
Although the CRT has resolution limits much ;lower than optical systems, the
of a CRT for change detection has certain advantages for processing
e information, such as enhancing and clipping.
Resolution of the entire system could be improved so change detection
as well as viewing can be done at maximum resolution. This might require
great improvement in the CRT or perhaps the development of some other
method of change detection in which a CRT is not used.
Amendment to the present contract will enable us to get a Change
Detector with improved resolution with little delay in the delivery date.

Development of a Change Detector with significantly greater resolution is
likely to require components not yet available and require a completely
new design. This will take a large amount of money and probably two or
three years from the present time.
With the delivery of the Change Detector early next year, we will
have the opportunity of working with it. There will be some problems en-
countered in its use that can be resolved only with experience. This use
will provide important data to be incorporated in the design of any future
Change Detector.

* - After conference at his ice upon returning,~~ called
' delay the preparation of a proposal
for the feasibility study for a high resolution Change Detector. Right
now they are to submit separate estimates for feasibility studies for
Change Detectors with two different levelee of higher resolution.
