Optical Instrumentation
Hyperspectral Imaging System
Fast, real-time multispectral and hyperspectral imaging
is now possible for spectral identification, target selection,
identification and discrimination. The imaging acousto optic
tunable filter (AOTF) and spectrally adaptive light filter
can be tuned for specific target selection.
Application: Satellite imaging, low contrast
and camouflaged object detection, natural and man-made object
discrimination, hazardous gas, environmental contamination
monitoring, soil quality / contaminates, and medical tumor
detection.
Availability: In-house working prototype,
ready for OEM application / licensing
Autofocusing Liquid Crystal Lens
POC has developed the autofocusing LC lens with a system which
is electro-optic and mechanically “free focusing”.
The LC lens approach features a higher numerical aperture, with
a less complicated electronic feedback and an object lens which
is less complex. The user will find this system much easier
to use with no moving parts, and with greater focusing precision.
This is all done automatically and virtually unnoticeable to
the viewer. Application: Autofocusing instrumentation,
night vision goggles, gastroscopes, microscopes, range finders,
cameras, and binoculars. Availability: Lab demonstration available.
Requires NRE for OEM implementation.
Omnidirectional Robotic Beacon Eye (ORB)
ORB is a wireless optical communication system with a 360°
field-of-view and at a 15° elevation. Through line of
sight, near-infrared ORB with light modulation, transmits
an optical, personal signature and survey information. ORB
is miniaturized, requires low battery power and can not be
jammed.
Application: Robotic surveillances, common
knowledge communication and wireless optical communication
network.

X-Ray Optics/Imaging (LEXIS)
The “Lobster-Eye” X-ray Imaging Sensor (LEXIS)
collimates, focuses, provides better control and greatly improves
transmission efficiency of X-rays. LEXIS can focus soft and
hard X-rays in the range from 1keV to 140 keV. The collimating
hard X-ray optic combined with the X-ray detector (i.e-microchannel
plate), significantly lowers the exposure dose, while significantly
increasing spatial resolution. At the emitter side, the collimating
optics increases flow of X-rays for deeper penetration through
industrial samples, with the same X-ray tube.
Application: Industrial and security scanning,
medical radiology, and X-ray vision systems.
Availability: Lab research completed - demonstration
ready in twelve months.

microchannel plate is scalable to a much larger (4”
x 4”) area. The Si-MCP can also be used as a soft X-ray
collimating and focusing optic. The microchannel structure

deviation with a precision of 20 microns for objects, moving
at a speed of 440 m/sec (e.g. can track a bullet). ITT has
a quick reaction rate of less than 0.001 seconds and would
warn a soldier of an oncoming sniper bullet in time to move
or get out of it’s intended path.
Application: Bullet / target tracking for
anti sniper applications, fire arms, missile, and sports equipment.

Sensor Systems
Sand Particle Detector (SAND)
Designed for the M1 Abrams tank, this special acoustic
sensor measures the number and size of dust / dirt / sand
particles that come through the air filtering system. These
particles can be dangerous to the engine, and can cause critical
failure. The SAND system is a sophisticated electonic signal
processing system capable of measuring 1200, 5um particles
/ ft3. SAND works at a frequency wherein scattering is a function
of the ratio of particle size to wavelength, producing a clear
correlation between the strength of the scattering signal,
the concentration of particles, and particulate size.
Application: Dust detection system for heavy
duty military and commercial vehicles such as tanks, trucks,
plus heavy earth moving, and agriculture equipment. Also environmental
and health applications such as conditions found in mines.
Availability: Completing proof of concept

Immunofluorometric Drug and Pathogen Detection System
This system offers quantitative detection and monitoring of bacterial and viral
contamination as well as drugs in saliva or sputum, thus avoiding
problems with blood and urinary testing. This discrete system
uses a saliva or sputum sample, instead of urine or blood
to detect drugs or transmission of food born or respiratory
diseases. The POC system is highly sensitive (5 pg/mL - e.g.
marijuana and cocaine), highly specific, and can produce test
results in under 10 minutes. This system is portable, compact,
easy to use, and features a low cost mass producible cartridge.
Application: This system can easily measure
bacterial and viral contamination prior to entering hospitals,
cruise ships, schools, food industry facilities and military
installations. Drug, hormone and metabolites detection for
pharmaceutical and health care industries. This can also be
used to detect biological and chemical warfare agents.
Availability: Completing research.
Corneal Mapping System
The POC corneal mapping system will take real-time precise
measurements of the corneal shape during photorefractive keratotomy,
which is widely used to correct visual acuity. Current instrumentation
can only measure the corneal shape several days after the
procedure. The POC system can be used during the procedure
and can accommodate the uneven surfaces caused by the laser
procedure. Our solution provides accurate corneal mapping
during lasik procedures and gives corneal shape information
with the amount of removal tissue. Doctors can take immediate
measurements and make corrections with greater accuracy during
the procedure.
Application: Speckle interferometer for
corneal mapping and precise measurement systems.

combined with a massively parallel automated analysis array
yields ultrahigh throughput. The microchip will consume only
nanoliters of sample and reagents.
Application: Simultaneous assay of multiple
cancer-related protein markers in unpurified sample body fluids
and/or tissue lysate in hours. MPA facilitates early diagnosis
of cancer, improve tumor treatment efficiency and save life
of thousands of people.

in hormonal status of lab animals. Laser Lancing is a painless
and stress free way to acquire a true profile of physiological
parameters. This approach will improve the study and test
results of biological and medical research. Eventually the
POC lancing devise can be used in biomedical research at universities
