Paper Abstract

Fraunhofer Line Discrimination (FLD) is a passive optical spectroscopy technique with potential for battlefield remote sensing of aerosol targets, as well as other military and academic applications. The Spatial Heterodyne Interferometer for Emergent Line Discrimination Spectroscopy (SHIELDS) will provide real-time remote sensing using FLD. The unit will be contained in a man-portable box to provide heads-up detection of dangerous chemicals in target clouds. The spectrometer employed will be the monolithic Spatial Heterodyne Spectrometer (SHS). One SHIELDS unit will feature a monolithic SHS to look at the 589-nm Solar Fraunhofer doublet. A second monolith will be built, using novel designs, to look at several different Fraunhofer lines of interest, all in the visible (H-b, Mg, H-a). The finished monoliths will be tested on laboratory targets, and the final complete SHIELDS unit will be further tested in the field.
