ELEVENTH MONTHLY PROGRESS REPORT
IMAGE QUALITY METER
17 April through 17 May 1961
During the period covered by this report, the fabrication of
the instrument was completed, with the exception of the potentio-
meter which provides the oscilloscope sweep voltage, the foot
pedal assembly for lowering the platen, the vacuum platen, the
drive motor for the rocking mirror assembly, and the spot mask
reticles. These itmes will be added as soon as received from the
vendors involved. Considerable difficulty was encountered in the
optical alingement and adjustment; it became necessary to add
light shielding assemblies in order to minimize problems introduced
by stray light. Some modifications were required in the condensing
system positioning in order to properly Illuminate the spot mask
reticles. Shielded wires have been added to some of the cabinet
wiring to minimize electrical signal pickup. A cooling problem was
encountered in the photomultiplier assembly"; this is being alleviated
by air ducts and a modification 'viithlh-... the assembly which allows
lower dissipation of heat.
DECLASS REVIEW by NIMA/DOD
The instrument is undergoing further testing and de-bugging, and
will be delayed in its delivery of these unexpected difficulties.

plicr tube and the input signal variations are then mea-
sured electronically with an analog computer. Results are
observed on three meters (acutance, granularity, reso-
lution). The microdensitometer trace on the oscilloscope
may be photographically recorded at operator's option.
Carefully Engineered - Heavy duty circuitry is designed
for easy access and quick testing. A massive steel frame
immobilizes the optical system, fixing it permanently
against mis-alignment due to shock and vibration. Con-
sole is on 'asters for easy movement about laboratory.

WESTWOOD DIVISION Ii: HOUSTON FEARLESS
The new Houston Fearless electronic Image Quality
Meter accurately measures granularity, acutance and
resolution of black and white photographic transpar-
encies rapidly and automatically. Accommodates cut
and roll film up to 18" wide.
Basic Evaluation Tool -The Image Quality Meter per-
mits holding standards for controlled performance of all
photographic systems - as basic to the photographic
instrumentation field as the oscilloscope is to electronics.
The most intricate systems can then be tested and evalu-
ated precisely to the rigid standards established by this
instrument.
How it Works - The film image is scanned with a mov-
ing spot of light; the light is collected in a photomulti-
