3 June 2011 iCATSI: a multi-pixel imaging differential standoff chemical detection sensor
Author Affiliations +
iCATSI is a combination of the CATSI instrument, a standoff differential FTIR optimised for the characterisation of chemicals, and of the MR-i, the hyperspectral imaging spectroradiometer of ABB Bomem based on the proven MR spectroradiometers. The instrument is equipped with a dual-input telescope to perform optical background subtraction. The resulting signal is the differential between the spectral radiance entering each input port. With that method, the signal from the background is automatically removed from the signal of the object of interest. The instrument is capable of sensing in the VLWIR (cut-off near 14 μm) to support research related to standoff chemical detection.
