Night Vision Technology

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 (passive)
Low Light Level Imaging (passive)
Low Light Level Imaging (active)
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 (optionally pseudo color).
Thermal Imaging night vision cameras operate on the principal that all objects emit infrared radiation, proportional to the temperature of the object. The Thermal Imaging camera uses the infrared radiation from the targets of interest and the background scene being viewed, and turns this information into an image map of minute temperature differences of the scene and target. This Thermal Vision technology uses what is recognized as the Mid-band and Long-band of the thermal radiation spectrum. The warmer an object is (for example, a person's body), the more radiation it emits relative to a colder background, and vice-versa.
Thermal Imaging cameras detect thermal radiation and even the smallest differences in temperature become visible and therefore can provide a clear image from a scene in total darkness.
CONTROP's Thermal Imaging cameras include sophisticated image enhancement algorithms, thus allowing the production of extremely well-defined image of the smallest temperature differences in the scene, while at the same time can handle a very large dynamic range within the scene (large variation of temperatures in the scene).
