Homeland security R&D & Image fusion

What is homeland security?

Homeland security refers to the national effort to:

  • Prevent (terroristic) attacks
  • Reduce the vulnerability of a country
  • Minimize damage from occuring attacks

Critical infrastructure protection forms an obvious and integral part of homeland security. Typically, infrared cameras and short-range radars are included in intrusion detection devices.

The use of multiple technologies increases the effectiveness of a detection system and reduces false alarms. Especially when operating in various weather and lighting conditions, a combination of different infrared wavelengths (image fusion) offers considerable benefits.

Why image fusion?

Long-wave infrared (LWIR) thermal cameras are excellent in detecting thermal signatures. Thermal cameras only see differences in thermal emission between a “target” and the background and they do not rely on ambient lighting conditions.

Short-wave infrared (SWIR) cameras can see through fog, haze and smoke, and because SWIR imaging is based on reflected light, it returns more details compared to LWIR. SWIR images resemble visible black-and-white images and are therefore easier to interpret than thermal infrared images.

With image fusion between SWIR and LWIR, you will have the best of both worlds. This results in excellent detection, recognition and identification of targets.

What do we offer?

Image fusion of SWIR and LWIR is still mainly in a development phase. The advantages are clear, but cost (mainly for the expensive SWIR technology) also plays an important role. Additionally, we have developed intelligent algorithms for efficient overlays of SWIR and LWIR images, with the same field-of-views.

Both our XSW or Bobcat-series (SWIR) and XTM or Gobi-series (LWIR) employ the same electrical interface (CameraLink or GigE for example). This makes these cameras, next to their small form factor, easy to integrate into an image fusion system. Additionally, our Xeneth SDK (Software Development Kit) will be a useful tool for the set-up of any image fusion system.

What features are needed?

  • Image format
    Image format and lens focal length, in both wavelength bands, will define the field of view of the image fusion system
  • High thermal sensitivity
    Thermal cameras need to have a high sensitivity level (low NETD) to detect the smallest temperature differences
  • Low noise level and high dynamic range
    A low noise level assures a high sensitivity, while a high dynamic range results in a high image contrast
  • Rugged and small cameras
    The ruggedness and size of our infrared cameras are important features for an imaging system. The smaller the camera, the easier it is to integrate. Rugged cameras withstand harsh environmental conditions
  • 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

World's first InGaAs camera photon emission microscope

Xenics enabled Semicaps to realize the world's first InGaAs camera photon emission microscope in 2004. Since then Xenics and sInfraRed have supported us in our endeavors for better sensitivity and resolution in photon and thermal emission microscopy.
