Night monitoring system technology using pulse later lighting to
detect an object at a long distance
Client / Market
- Domestic companies with demand for night monitoring device (surveillance camera,
security system, etc.)
- Companies with demand for portable day/night monitoring device for military use
- Civilian industry (securing vision through smoke during fire, night vision for car,
object alarm system for driving in fog or rain, unmanned night safety and security
field, etc.)
Necessity of this Technology
- Existing night monitoring system uses a large lamp or LED with a large divergence
angle, which is insufficient for seeing objects at a long distance.
- The U.S. currently has the best technology for long distance night monitoring
system, but the country has banned exporting this system, and it is unlikely that ban
will be lifted in the future. If long distance night monitoring system can be developed
in Korea, it will be a promising exporting item due to the export prohibition of
corresponding system in the U.S.
Technical Differentiation
- Existing night monitoring system used a lamp or LED, but this technology uses laser
which boasts better straightness than other light sources and enables to see objects
from afar.
- Using near infrared laser that cannot be seen with eyes, it can visualize objects in
the far distance, which makes it suitable for military use.
- Power consumption decreases with the use of pulse laser.
- Portable-size module is developed.
Excellence of Technology
- Development of long-distance night imaging source using surface light emitting
diode (VCSEL) is completed.
- With the narrow wavelength range, image can be obtained using a filter in fog or
when interrupted with flame.
- Can be used for far distance up to several hundred meters.
- Using a device with this technology applied, the lower-case letter ‘a’–size of 70 cm×
60 cm-was photographed from approximately 500 m ahead at night both when the
IR laser was on and off. It was confirmed that the letter ‘a’ could be detected when
the IR laser is on.
