CONTROP Precision Technologies Ltd. has become a leader in night vision technology since the company's inception in 1988.
The term "night vision" refers to the ability to see in situations where there is limited or no light. This capability is critical in many security and defense applications and CONTROP night vision cameras are known to provide the required solutions.
The three most common types of night vision technologies are Thermal Imaging, Low Light Imaging and Near Infrared Illumination.
CONTROP's Thermal Imaging Cameras
are based on a night vision technology which does not require any light what-so-ever. These cameras produce a black and white image even in total darkness.
Thermal Imaging night vision cameras operate on the principal that objects emit infrared energy which influences the temperature of the object. The thermal imaging camera uses the infrared energy from objects and from the scene being viewed and turns this information into an image. This night vision technology captures the upper portion of the infrared light spectrum which is emitted as heat from objects rather than as light from these objects. The warmer an object is (for example, a person's body), the more light is emitted. The cooler an object is (for example, a building that is in the shade and not heated by the sun) the less light is emitted.
Thermal imaging cameras detect thermal radiation and even the smallest differentiation in temperature becomes visable and therefore can provide a clear image from a scene in total darkness.
CONTROP's thermal imaging cameras include image enhancement algorithms which collect minute amounts of light - including the lower portion of the infrared light spectrum - amplify them to a level which can enhance the image obtained from the thermal imaging camera.
