EXPLORATORY DEVELOPMENT LABORATORY BRANCH 1967 PROGRAM-
1967 EDLB Detail Program (Revision):
In the 26 May 1966 POP meeting, the following program for the
Exploratory Development Laboratory was determined, and priorities
assigned in the order of their listing. These projects are specific
items, selected through POP suggestions and through natural evolutions
of laboratory ideas and current investigations. The completion of
current 1966 projects, which may overlap slightly into 1967, is not
detailed in this list. Current projects which will dot terminate
before l August are included in the list.
. l) PHASE GRATINGS: The development of prototype diffraction
gratings for use in the Direct Image Viewer and
subsequent modifications. The techniques employed will be
photographic or glass etching. Current efforts indicate
a high probability of success far the latter method.
2) MICROSCOPE MTF STUDY: This study is concerned with
evaluating most NPIC microscope equipment through analysis
of each instrument's MTF. Included are stereomicroscopes
and microstereoscopes, and the investigation will cover as
much of the magnification range of each as possible.
3) SCREEN EVALUATION: Under current development or study there
are four screens or screen material for use in several viewing
applications. Before continuing with subsequent development
for any or all these materials, an in-house evaluation will be
made to assess their potential for future applications.
~+) LAMP PREFERENCE STUDY: To guide future developments of
viewers and viewing devices, insofar as the light source(s)
is concerned, a study will be made of PI preference. This
study will be aimed at determining if a preference exists;
if it does, is it significant enough to affect future
equipment performance specifications? "~
5a) STUDY OF COLOR REPRODUCTION MATERIALS: Increasing probability
of color materials coming into the center, with subsequent
reproduction requirement, requires a,n assessment of current
state-of-technology in that area. Having determined the eventual
requirements, the studies will aim at satisfactory solutions
without restricting them to a single manufacturer or product.

5b).COLOR VIEWING STUDY: To inspect color materials and
ascertain the effects of the variation in color balance,
a viewing device which permits adjustment of color values
is required. The design of this equipment will follow the
proposed of 20 August 1965.
ISODENSITRACER INVESTIGATIONS: This considers the development
of a color version of the IDT, the IDIOT, as well as general
investigations into utilizing the instrument to perform
gradient removal.
7) MONITOR'S PORTABLE EVALUATION KIT: A kit will be assembled
for use of the monitors in the Development Branch for field
evaluation of equipment under development. The kit(s) will
include resolution targets (in proper format), length standards,
B&W and color step tablets, MTF testing device, equipment
. for photometry, and a slide rule or similar computing device.
$a) OPTICAL CHANGE DETECTION: The superimposition of two related
transparencies through projection can serve as the basis for a
technique to eliminate their subject similarities and~or
display their differences. Color addition and subtraction
will be included, and the process examined through the
photographic variables as well as the system MTF.
$b) BLINK COMPARATOR: The flicker viewing of two related
transparencies to make their differences stand out has shown
some promise. In pursuit of the general change dete coon
problem, this method could prove highly useful. Initial
studies will be on the illumination control circuits. Further
studies will consider brightness levels, flicker frequencies,
the temporal and spatial transfer functions.
) REMOTE FILTER SELECTOR: This device will be designed and
fabricated in or through the EDLB to improve the performance
(in time~~of the Durst Enlargers in PSD~PLB when using the
enlarger in a color mode. The device will remotely select
and mechanically place filters in the optical system, to
replace the present manual technique.
10) MODULATID LIGHT: To establish the basic parameters of modulated
light viewing and reproduction, a study will be carried out.
Tt will aim at providing a summary of the state-of-technology
in this area, and provide the basis for DB action in subsequent
development programs. The potential uses of such a technique
will be the prime focus for these studies.

l1) FEASIBILITY OF TRANSPARENT FILM CAN LIDS: Towards the
elimination of redundant labelling, one aspect of the use of
transparent lids for film cans will be investigated; the
transfer of identification from one reel to another.
12) ADJACENCY EFFECTS: Considerable emphasis in 1966 was given
to the study of adjacency effects, particularly their
characterization through mathematical models. This program
will be summarized, the results of sponsored research evaluated,
and a report issued which establishes the current state-of-
technology. The continuation of further work by the EDLB is
not cca~templated until a six-month review of the branch effort
takes place.
In addition to these specific problems, work will also be carried
out in three areas which are in the staff's long-range interests. As
results accrue, those which are applicable to Development Branch efforts
will be made known. These studies are generally carried out in parallel
with the specific problem assignments but do not have their immediacy.
When it bec ones necessary to allot more time to these areas than is
otherwise anticipated, the subject will be raised at a POP meeting for
approval.
1) DEVELOPMELVT OF ANALYTICAL METHODS; This is the chief problem
of the Analytical Support Section, but is currently related
to specific problems in support of investigating scientists.
2) AMPLITUDE~PHASE IMAGERY INVESTIGATION: The problems of
fluid-gating, relief images, relationship of phase to density
and specific coherent illumination problems are all to be
considered. With the increase in performance capability of
optical systems, the problem of relife images is assuming a
more fundamental importance than heretofore. A continuing
branch interest is maintained in this area.
PARTIAIZY COHERENT IMAGERY: In anticipation of the Image
Analysis .Program, the branch must be prepared to evaluate
and utilize the results of the fundamental investigations
proposed by the contractor. Since the effects of partially
coherent illumination are not fully understood nor predictable
(and will be the basis of the contractor's work), internal
theoretical and experimental investigations will be required
to provide a solid basis for understanding and implementing the
contractor's recommendations.
