MR-i Hyperspectral Imaging Spectroradiometer

Brand: ABB Group

With over 40  years of innovation and being recognized as a world leader in spectroscopy, ABB is expanding its line of remote sensing products with a newly developed FT-IR hyperspectral imaging spectroradiometer operating in the infrared.

Based on the MR-Series product line, the MR-I offers accurate spatial, temporal (rapid scanning), spectral and radiometric information of infrared targets.

While conventional mono-pixel FT-IR spectroradiometers offer unique performance such as higher spectral resolution and enhanced sensitivity over the instrument field of view (FOV), multi-pixel FT-IR hyperspectral imagers now extend possibilities in infrared characterization. They provide accurate spatial characterization of a target’s signature by spatially resolving the essential characteristics over the observed scene.

The captured data is further exploited by combining the spectral and spatial information of the scene. As a result, an FT-IR imaging spectroradiometer has the unique capability of generating 3D images (2D images with spectral bands in the Z axis) providing a spectrum with every pixel of the mapped scene.
Features
  • Wide spectral range (1–15 µm), covering LWIR to NIR
  • High spectral resolution, (1 cm−1) equivalent to a filter radiometer with over 9000 channels
  • High radiometric accuracy and stability of response over a wide dynamic range
  • High NESR sensitivity, allowing characterizing weak signal in short time periods
  • High dynamic range and signal-to-noise ratio;
  • High time resolution through fast scanning, allowing measurement of the evolution of rapidly varying target signatures
  • High spatial resolution with extended FOV homogeneity, leading to better accuracy no matter where the target is in the FOV
  • High reliability: Compact and portable for easy deployment in field operation and airborne operation
