Schematic drawing of thermal and SR IR sources alignment features on a FTIR imaging system equipped with a FPA detector. A higher magnification level (36× versus 15×) induces a loss in detector illumination by one order of magnitude whatever the source considered, but SR covers much more of the detector for its brightest part, thus enhancing the SNR. Images were obtained at the DAFNE Light Laboratory at the Laboratori Nazionali di Frascati, Italy.
