Abstract

Deep UV Raman spectroscopy has made significant strides from large lab-based systems to compact, highly ruggedized instruments being used for planetary exploration such the SHERLOC instrument on the Mars Perseverance rover. The combination of deep UV Raman and fluorescence spectroscopy has been particularly interesting as it offers a unique solution to rapidly search for targets of interest. This was previously demonstrated with biological detection using proximity and standoff deep UV fluorescence/Raman mapping devices. More recently we have been expanding this effort, to move into explosive detection. This talk will discuss the fundamentals of the detection methodology, the advantage of combining and collecting simultaneous deep UV Raman and fluorescence, and sensitivity of the new systems.
