ABOUT
OPTICAL ENERGY TECHNOLOGIES INC.
OET was organized in 1984, and since then has been
engaged in the manufacture of a patented,
non-tracking concentrating solar collector, and the
installation, and service of all types of solar energy systems.
In 1997, OET was reorganized to provide expanded
electro-optical, electronic, mechanical, and
instrument system design and development services from concept
definition, system and worst case analyses,
design, fabrication, and test of electro-optical instruments
and/or subsystems of larger electro-optical systems.
OET has a staff of interdisciplinary senior level
engineers/managers, having a cumulative experience of
over 150 man-years, who have worked closely together for over 7
years.
SPACECRAFT
SOLAR POWER PANELS
OET is currently developing,
on its own funds, its patented high
power, 12/1 trough concentrator for GaAs solar
cells, with a
"Figure of Merit" of greater
than 100 watts/Kg. of panel weight
(four times that of current spacecraft
solar panels) with a unique
folding configuration. OET has also
developed its
patented 2.8/1
pyramidal concentrator solar collector
flat plate solar panel for
spacecraft having a "Figure of Merit"
greater than 150 watts/Kg.
(Five times that of current solar panels.)
SPACECRAFT SUN
SENSORS AND ATTITUDE SENSOR SYSTEMS
Also in the prototype stage and flight qualified, is a patented
two
axis, high accuracy sun sensor for use at any orbit,
with an 100° diameter field of view with different models
providing readout accuracies over this field of view of ±
0.5° to ± 0.05° 3s even at low earth orbit, where the earth
albedo normally produces inaccuracies. This sensor uses
a proprietary algorithm incorporated into the spacecraft
computer to provide this accuracy and allows the optical
head of this sun sensor to have a weight less than 1.4 ounces
(<40 grams). One of these sensors will fly on the
CUBESAT picosatellite developed by CALPOLY University, San Luis
Obispo in November 2004. Also recently
developed is
a single
axis infrared earth sensor weighing less than 100
grams and providing ±1° of accuracy at null
attitude for low altitude circular orbits. Four of these earth
sensors are incorporated into the micro-sats being
developed by Michigan Technical University and Taylor
University for flights on the Space Shuttle.
ENERGY STORAGE
MAGNETIC BEARING FLYWHEELS FOR GROUND OR
SPACE USE
OET has also conducted initial development, using a
combination of in-house funds and a grant from the
State of Connecticut Advanced Development Authority, of a
combination energy storage flywheel/attitude control
reaction wheel system using semi-passive magnetic bearings, on
which a patent has been granted. These semi
passive magnetic bearings reduce the electronic complexity of
the required levitation control circuitry relative to
existing competitive active magnetic bearings by a factor of
5/1, thus reducing recurring costs and increasing
reliability commensurately. The result of this program to
date is a full scale mechanical mockup using the passive
magnetic bearings only, with the flywheel driven by external
means.
COMMERCIAL
ELECTRO-OPTICAL INSTRUMENTS
OET has also developed and delivered commercial,
electro-optical spectral radiometer instruments for
field use, providing discrete spectral filter responses in the
1.0 to 5.0 µ m infrared wavelength region. It has also
developed and delivered three, state-of-the-art,
spectro-radiometers covering the infrared wavelength region
from 1.4 µ m to 14.2 µ m, able to generate 10 spectra
per second, with a spectral resolution better than 0.1 µ m.
INFRARED BLACKBODY
SOURCES
OET also offers cost effective 1.25" and 2.00" diameter
blackbody IR sources with temperatures of 1000 °C
incorporating a built-in optical chopper priced as low as
$3200- with chopper and $3,000- without chopper. Custom
blackbody sources can also be supplied.
6000K SOLAR
SIMULATORS
OET has developed a family of 6000K solar simulators
with small solar angular subtenses for testing of sun
sensors, solar panels, and small satellites. The apertures of
these simulators range from 5" diameter to 27.5"
diameter. All of these simulators generate 1.0 solar constants
in space, and can be used inside thermal vacuum
chambers.
COST EFFECTIVE
ELECTRO-OPTICAL DEVELOPMENT SERVICES
OET also offers quick response and cost effective
development services using its highly qualified staff,
for commercial or spaceborne electro-optical instruments. Call
us or email us and we'll be glad to discuss your needs.
