new table (HROOT) the scanning unit redisplays for printing purposes a program
med portion of the image area being scanned by the input scanners. Either a
Compilation Mode or a High Resolution Mode may be used. In the former, the
orthophoto, elevation chart, and taped stored elevation data are produced simul
taneously; in the latter, the scan is optimized for maximum output resolution
(this mode may be used sequentially with the correlation scan during compilation
or optionally during a playback printing mode following a complete compilation).
c. The Air Bearing Micron Mensuration Stage instrument has a near-
interferometric measurement capability. It is a compact, light-weight, precision,
two-axis system providing high positioning and measurement accuracy--initial
accuracy is maintained with virtually no maintenance nor recalibration. Support
and guidance of the X-Y stage assembly is accomplished by frictionless, self
cleaning air bearings. Travel in both X and Y direction is possible. A variety
of commercially available microscopes can be used to facilitate measuring
operations. Binary coded decimal position information, originating from ab
solute metering scales on each axis, is amplified and processed by a remote
electronics unit. The outputs are compatible with a visual in-line decimal dis
play and/or a typewriter printout unit.
OPTOMECHANISMS, INC.
The OPTOmechanisms, Inc., Plainview, New Jersey, USA, has introduced
a Universal Imagery Exploitation Viewer (Model 571 U). It is a compact, pre
cision viewing and measuring instrument incorporating high resolution optics with
fiber optic cables, image enhancers, and related mechanisms. Five functional
categories make up the instrument, namely, imagery viewing, film illumination,
film handling, tracking system, and measurement systems.
a. Imagery Viewing. A total of seventeen variations in viewing are avail
able including use of TV displays, complete image rotation, switching of left and
right imagery, overlapping magnification over a wide range, use of varied film
and glass image formats, and use of black and white, color, and infrared vertical
and oblique imagery materials.
b. Film Illumination. Two illumination stations are provided with general
and high intensity light sources. Controls allow for variable illumination at each
station to accommodate imagery of varied intensities. Fans and heat dissipating
mirrors regulate temperatures within practical limits.
c. Film Handling. Features include manual and motorized film transport,
semiautomatic film looping, glass platens with pressure plates and vacuum controls.
d. Tracking System. Variable speed transport and precise positioning
of the left and right objective assemblies are possible through the use of a "joystick"
control. Stereotracking with left and right imagery of different orientations is
possible.
e. Measurement Systems. The instrument provides for the incorporation
of three measuring systems and one calibration system.
