Gated viewing laser camera systems
- Gated viewing pulsed laser camera / active television for professional users
- Capability to see through snow, rain , fog and smoke by time discrimination
- No need for ambient light as the laser gives the needed illumination
- Increased penetration by factor 3 to 5 compared to alternatives or the eye
- Possible to see through vegetation , masking nets , curtains etc.
- Special models for sub sea use penetrates up to over 100 meter depth in Atlantic water.
- Almost immune to blinding from foreign light sources
- Distance to illuminated zone can be set and measured like a distance meter
- Possibility to have image as negative or positive image / background illumination
- In operation in Norway France, Sweden, Greece and Lithuania , in marine applications
This technology can easiest be explained that we freeze or strobe a short laser pulse in its flight at speed of light. This is viewed by an image intensifier where the shutter is controlled with nanosec. accuracy. The shutter can be opened and controlled precisely. This makes it possible to decide where you want to see and how far away. The depth of the illuminated zone can be controlled. By this technology you can control where you want to see and obstacles out side this area are black and not illuminated. Compare driving a car in heavy snow fall. Lights gives reflexes making you close to blind. Here you can illuminate behind the snow and see objects as negatives which is very comfortable
Our systems are available in 3 versions optimized for each purpose. Aqualynx is optimized for submerged applications. Sealynx is optimized for marine search and rescue, Nordlynx is optimized for airborne search and rescue and low altitude flying.
These products are difficult to explain so the professionals operator in the applications areas really understand the advantages. When the systems is showed every one is astonished and impressed.
What is gated viewing ? Example by a simple drawing in a marine application.
The bushes are about 30 m away and in front of the illuminated zone. They becomes black as a negative. The negative image is very efficient in seeing objects hidden inside vegetation and other obstacles.
This image was impossible with the best on the market generation 3 goggles as they will see reflexes on the front of vegetation and not what is inside. This is the most common situation and the gated viewing laser cameras are always far better than any intensified system used today by police or military staff. Tests in Sweden have detected persons 50 meter inside a forest where the sky is shining from a close by city.
The white vertical lines are sticks in the water used for the boats. They are about 100 in diameter and 1 meter long. They are about 300 m away from the camera.
Behind them there is a small bridge. Behind the bridge there is a sailing boat. The mast of the boat is the vertical white line.
In the background there are some houses with lights These lights do not disturb the intensifier.
This is a typical situation for many search and rescue situations where there are some illuminated spots in the field of view.
The gated camera is almost insensitive to this type of illumination .
