Xlin-1.7-3000 for earth observation The Xlin-1.7-3000 detector is specifically designed for earth observation to reveal lots of detailed information on vegetation, clouds, humidity and other atmospheric conditions.
Sensors for remote sensing by Xenics The main activities of Xenics are the design and manufacture of linear arrays, FPA and cameras for the Short Wavelength range (SWIR), based on InGaAs detectors. Exactly this wavelength band is of high interest in the remote sensing of vegetation properties. The water (vapor) content of the atmosphere causes a strong absorption at 1.45 μm, but above this absorption peak, the reflectance in the [1.5 – 1.7 μm] band is very interesting to determine the liquid water content in the plants and for the identification of tree types and plant conditions. For the more Mediterranean area the SWIR band is also important to detect wild fire affected areas and even for the detection of active fires.
Space developments resulting in industrial camera platforms Xenics, involved in several space projects such as Proba-V, is responsible for the design and development of the short-wave infrared detectors. A novel high resolution InGaAs line-scan camera from Xenics conquers many applications in the near infrared.
EARTHCARE is a cornerstone mission of ESA to study the radiometric balance of the earth ecosystem Preparation of the Visible, Near Infrared and ShortWave Infrared detectors on Earthcare for the radiometric analysis of the earth energy balance
Xenics InGaAs SWIR detector is part of the Proba-V space mission Three Xlin-1.7-3000 linear arrays are launched into space aboard the ESA's Proba-V satellite (2013)
