1. This trip was made to complete the in-plant pre-shipment
inspection of the "Change Detector". The Detector was a roved for
shi ment on 23 September and
In this respec has produced. an acceptable product. A
summary of the design objectives and the actual results follows:
2. Because most of the numerical data in the contract are
design objectives instead of specifications, it was not possible
to make the inspection on the basis of meeting certain fixed numeri-
ca.l requirements. The re-shipment inspection was therefore made
to establish success in approaching the desired objectives. 25X1A

Correlation: et up two images with a, small amount
of "X", "Y", cale and 'Rotation" differences between the
images. When placed in the "Automatic Correlation" mode the
Detector correlated the images. There was a, small residual
error in the "X" direction which was due to misalignment of the
correlation mirror. This can be corrected, but is a, time-con-
25X1A
after the Detector arrives 'at the Center because the vibration
received during the trip may cause some misalignment of the
Detector.

3. The shipment will be delayed a few more days due partially
to the malfunction of a component and partially to a equire- 25X1A
ment that thorough photographic coverage be made of the Detector.
They will give us two sets of all still photographs.
Notes: *Because there is no conventional method of designating
attitude deviations as "plus" or "minus", the terms are purely
relative. The right film channel, which can be rotated in what
would be considered the "tip" direction, can rotate one degree less
in one direction than the other because of the location of one of
the film drive motors. This is due to the changes we requested in
the film magazines after most of the Detector had been designed and
fabricated.
**The design objective of 50 lines per millimeter has not
been met and probably will not be met. The two factors that have
caused this are:
(1) the left film "sees" the CRT raster at a, decided
angle (about 15 degrees) and the Detector therefore
uses the Off-axis resolution of the left-film lens
rather than the better, on-axis, resolution; and
(2) the flying spot scanner CRT focus coil is not at the
optimum location on the neck of the CRT. The focus
coil has been displaced to allow installation of
space for a, more optin;.um location. The 32 vlines Vper
millimeter were attained on the left channel which
is the worst.

a. The shipping costs are not art of the contract and
must be billed separately. The iNWransporta-tion personne2 5X1A
have estimated that the cost for so e use of a. moving van will
be moving van will probably be used because 25X1A
it wl prov e a. softer ride for the Detector with less
possibility of damage. A special "air-ride" tractor trailer
combination was considered but could not be used because a
minimum load of about 30,000 pounds is needed to properly
operate the "air-ride" device. The amount of insurance was
also discussed butthe undersigned advise at this 25X1A
was a, problem for' the ontract and transportation depart- 25X1A
ments in terms of wha. could be recovered in the event of a 25X1 A
claim. ill discuss this with the appropriate M 25X1A
b. The Detector probably will be shipped in one piece
because it will be easier to properly protect it during ship-
ment. This should not present a.n insurmountable problems for
us. Upon arrival in he Detector will be rolled, 25X1A
on its own wheels, a, ong the firs floor corridors to Room

Monday morning to start the "uncrating" and to perform the
final "tune-up". This will require five working days. During
this period it is expected that only P&DS personnel will be 25X1A
admitted to the checkout room.
