The XSW-320 SWIR module is a shortwave infrared OEM module with a resolution of 320 x 256 pixels and a pixel pitch of 20 µm.

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.
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.
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.
