Belgian company Xenics (Hangar 2, Stand A8), one of Europe’s leading manufacturers of infrared imagers and cameras, is introducing its SWIR (short-wave infrared) imaging technology to aerospace and security system communities in Africa.
SWIR imaging operates within the 0.9-1.7μm wavelength. Just like in visible imaging, a light source such as the sun, night glow or an eye-safe laser is required to make a SWIR image. It offers distinct advantages in the areas of enhanced vision systems (EVS) and in remote sensing.
EVS improve situational awareness around an aircraft, whether manned or unmanned, fixed wing or rotary, both in flight and when manoeuvring on the ground. The wavelengths used allow a pilot or UAV operator to see through fog, haze, dust and smoke. Applications for remote sensing include the monitoring of vegetation or for the exploration and exploitation of minerals.
SWIR covers a large dynamic range, uses conventional optics, gives improved identification and recognition, can image through glass (so can easily be cockpit or gimbal-mounted), delivers high frame rates and offers markedly better visibility and higher transmittance in poor atmospheric or weather conditions.
Hyperspectral imaging in the SWIR range opens new sensing applications for measuring environmental parameters. Xenics cameras using SWIR technology are well suited for reconnaissance, monitoring and exploration tasks and can contribute greatly to public safety and security.
