INNOVATION
The Intensified
Color Camera is a compact sensor which combines the capabilities of
high spatial resolution image intensification with color sensitivity.
This results in an improved imaging capability which retains color sensitivity
at low light levels.

ACCOMPLISHMENTS
- Conventional image intensifiers
provide a monochromatic image. In many situations, such as surveys
of space and earth, considerable information is contained in the
spectral data that would be lost in monochrome.
- With initial support from NASA,
we recently complete development of technology that intensifies
and preserves color information in images. The design is based on
a proprietary color filter and has now been conceptually extended
to real-time video, including IR sensitivity.
- System performance was demonstrated
by intensified "before-and-after" images. The "before" images were
in conventional monochrome. The "after" images demonstrated restoration
of color to the intensified images. One demonstration was produced
with 80 millilux of illumination. Another demonstration was produced
with only 15 millilux of illumination.

COMMERCIALIZATION
- InterScience is actively
seeking a partner to help commercialize its intensified color imaging
technology.

GOVERNMENT/SCIENCE
APPLICATIONS
- Improvements in the
sensitivity and resolution of image intensifiers has led to
introduction of the technology into a broad range of products.
At the present time, the principal application has been in night
vision goggles and gun sights used by the military and law enforcement
community.
- Increasingly, however,
it is finding a role in the consumer market for binoculars, in the
commercial market for surveillance, in the scientific market for
detection of very low intensity optical signals.
- For all these applications,
the ability to retain chromatic information would be of significant
interest, more so in some applications than others.
- Indeed, the ability
to see color from image intensifiers may create a greater demand
for image intensifiers. As has been noted, this capability can be
of significant value for space missions such as earth observation.
