EXTENSION OF SPATIAL FILTERING DEVELOPMENT FOR IMAGE ENHANCEMENT VIEWER
INTRODUCTORY BACKGROUND
"Extension of Spatial Filtering
Development for Image Enhancement Viewer," was submitted on 24 August 1961,
and amended on 6 October 1961. The amendment excised several proposed
development areas in order to concentrate on the one which appeared to be the
most immediately promising. This development was for application of the
rotating filter principle proved=out in the previous contract and reported in
IL-9019-1, "Design and Construction of Frequency Attenuating Filters,"
15 August 1961. The improvement of several of the optical and mechanical
aspects of the instrument was also proposed. The proposal was divided into
two Phases, the second to be initiated when and if the feasibility of the
mechanical, rotating filters was established. Upon award of the contract, work
was begun on Phase I.
PRESENT STATUS:
The mechanical and optical improvements of the instrument were carried out
successfully, but the mechanical, rotating filters did not prove feasible. The
results of the Phase I work was reported on 31 August 1962 in the 9043 Status
Report; Phase I, Final Report, and verbally to the contracting agency's technical
representatives approximately a month prior to that date. In a series of studies
paralleling the instrument modification, attempts were made (both analytically and
experimentally) to examine the general problem of image, or more precisely, edge,
enhancement. Because of the termination of the effort at the and of Phase I,
these studies were not completed, although useful steps had been taken towards
a formal statement of enhancement and an evaluation of the significant parameters.

Phase II work was not begun, pending review of the program, in the
form of a redirected effort, as outlined in the final report.
PRESENT INSTRUMENTAL REQUIREMENTS:
It has been reasonably well-established that the Image Enhancement Viewer
can be a useful tool when used in that type of operation for which it is
pre-eminently suited; edge enhancement. The attempts to make continuous-tone
spatial filters, while partially successful, have usually foundered on the
rock of image quality. Stated otherwise, a successfully operational coherent
optical system has too many inherent image-degrading qualities to provide images
of equal or higher quality than those obtainable through incoherent illumination
with a well-corrected lens. However, the enhancement afforded edges through the
use of high-pass occluding filters, and the possibility of linking this operation
with the technique of multiple-image printing renders the problem of extreme
image quality of something less than primary importance.
The present configuration of the Image Enhancement Viewer is a vast
improvement over the original model, the last two modifications having provided
the capability of image magnification, precise film and focal plane registration,
and significant increase in illumination level. On the other hand, there remain
several, additional modifications which could usefully be incorporated to
make the instrument more suitable for routine, operational use. These
modifications, and the reasons justifying them were listed in Section 5 of the
9043, Phase I final report previously cited. Under the terms of the 9043, Phase
II work statement, these modifications cannot be made since they require a redirected
effort, as a work statement. The following section therefore details the
suggested redirection.

PROPOSED REDIRECTION OF EFFORT:
There are two main areas of effort into which Phase II will be divided;
a) Instrument modification, and b) Enhancement studies. These efforts will
be made simultaneously, when possible, and the results of the enhancement
studies incorporated in the operation and maintenance manual proposed for the
equipment. The detailed breakdown follows.
Instrument Modification
1. Re-wire the Source Unit so that the input and output power leads
and the additional control wiring pass through an Amphenol
connector located on the forward unit plate.
2. Replace the present object Unit. with a new unit incorporating
the following features: a) Selsyn positioning of the object
vertically and horizontally, a total of two inches travel in
both directions, b) separate the collimating lenses in order
to operate in the correct Fraunhofer diffraction mode and to
facilitate auto-collimation adjustment. The unit will be
capable of handling carriers for film and plates. The carriers
will be free of strain.
3. Install two new occluding filters in the filter unit, to be of
0.020 and 0.010 inches in diameter (nominal), approximately.
This will extend the filter range by a factor of four (4).
4. Replace the three wooden bipods by two steel pedestals, to
be anchored permanently at the contracting agency's facility.
This will be shock-mounted and vibration-isolated as per the
agency's building requirements.

5. Replace the present control panel by a new unit which is in
the form of a wheeled aonsel4T? This will incorporate all
the power supplies and associated switches and transformers.
It will place all the electrical power and control devices
together and facilitate maintenance and simplify operation.
6. Provide current regulation to the DC power supply which eliminates
necessity for prolonged and supervised "warm-up" time by
skilled operators.
7. Install necessary cabling modifications.
8. Carry out minor miscellaneous engineering changes which will
improve the general usefulness of the instrument, but are not
sufficiently important to list here.
9. Prepare an operating and maintenance manual which will bring
the instrument up to date and permit full utilization of
the latest modifications. The results of the enhancement
studies will be incorporated as they apply.
10. Metal-'finish the instrument to provide protection against
humidity, rust, and similar problems.
ENHANCEMENT STUDIES:
To complete the studies of edges and edge enhancement initiated under
Phase I, it is proposed that the experimental work continue on edge enhance-
ment through exposure addition and transmission multiplication. This study
will examine the four basic enhancement possibilities, and will particularly
be concerned with their inclusion in multiple-image printing. It is expected
that the results of these studies will provide a final evaluation of the
Image Enhancement Viewer usefulness, with a specification of the parametric
effect of high-pass occluding. spatial filters on enhancement.

PHASE II SCHEDULE
Phase II as outlined above, will be complete six (6) months from date of
award. Shipment to contracting agency's establishment will take place subsequent
to this period, at his convenience. All manuals, spare parts, etc., will be
due and deliverable at that time. The instrument will be assembled, installed,
adjusted, and calibrated by an representative, at the 25X1
contracting agency's establishment when delivered, or at a time specified by him.
