What are enhanced vision systems?
Clear visibility is of the highest importance in any surveillance, safety & security operation. Critical airborne, road and maritime operations can benefit from a clear view on the scene and the environment. The more “eyes” you have, the more you can see. Quite often the combined perception is better than the simple sum of individual observations.
VIS vs SWIR
What are enhanced vision systems used for?

Longer wavelengths penetrate easier through fog and smoke, as they are less obstructed by small particles. But the use of one single wavelength range also has its draw-backs.
Sometimes the thermal contrast of a scene can be low. E.g. twice a day a landing strip has the same temperature (emissivity) as the surrounding lawns. In a maritime setting objects take over the water temperature when they are immersed for a long time.
Passive or active SWIR imaging provides the necessary contrast at short(er) range. But when visible, SWIR and thermal cameras are combined, the fused images can reveal details which are not visible in either of the utilized bands.
Multiple cameras can be mounted in a fixed enclosure, on a light weight, agile gimbal or on a pan & tilt head. Image fusion boxes are then co-registering the images, resampling the information and fusing the pixel information. If better co-registration of the pixel is required, cameras or cores can be mounted behind a single broadband objective lens.

What do we offer?
In EVS (Enhanced Vision Systems) and image fusion applications it is important to use cameras with a small form factor and low power consumption for an easy integration into an imaging system.
We offer the Raven-640-Analog (LWIR) and Rufus-640-Analog (SWIR) analog cameras. These have a cross-section of less than 55 mm and consume less than 2 W. These camera are ideal solutions for refurbishment projects.
For those who are looking for a MWIR core, we offer the XCO-640. This MWIR OEM core is equipped with a selection of Sterling cooled engines and complement the product range of our XenicsCores.

SWIR Cameras Ensure Visibility Day and Night in Any Weather
Around-the-clock surveillance capability in any weather is a decisive operational ad-vantage for military and emergency services. In these and similar applications, SWIR cameras are well-suited for everyday use because they show superior results when compared with most other imaging technologies. To recognize and track objects of light-reflecting as well as thermal-radiating natures, SWIR cameras can be easily combined with thermal LWIR cameras and their images fused to enhance their content and validity. ——-read more Download document(234.83 KB)
