Paper Abstract

An IR spectroscopic imaging technique has been developed which combines a step-scan Fourier transform (FT) Michelson interferometer with focal plane array (FPA) image detection. The first reports utilized an indium antimonide FPA in the spectral region 3950-1975 cm-1. Mercury-cadmium- telluride (MCT) focal plane arrays are now commercially available, giving access to the spectral range 3950-800 cm-1, thus greatly broadening the application of the technique for chemical analysis in the mid IR region. This paper describes some of the instrumental considerations as well as applications in the use of an MCT array detector, for novel mid-IR spectroscopic imaging applications.
