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.

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 has also 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 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.

Our XenicsCores are even smaller and less power consuming. Our XSW-Series (SWIR) and XTM-Series (LWIR) have a cross-section of 45 mm and consume less than 1.5 W.

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. 

What features are needed?

  • Easy connectivity
    We offer standard digital or analogue interfaces for easy integration, operation and maintenance
  • Lightweight and compact design
    A crucial point for all system integrators. Our XenicsCores are very light and extremely compact
  • Low power consumption
    Power consumption can be an issue when integrating cameras into a (fusion) system. Our infrared cameras consume very little power and therefore easy to integrate
  • Flexibility for a broad range of OEM applications
    Our XenicsCores prove to be very reliable infrared cores. This makes them suitable for many OEM applications
