Abstract

Rapid acquisition of Raman spectra and Raman spectral maps of traces of compounds at proximal distances by a compact Raman system is demonstrated. The performance of the system was further improved by photographing the target, prior to data acquisition, allowing selective monitoring of spatially resolved particles and thus mapping at reduced sampling times, compared to raster-scanning. This spectrometer and its photo-guided sampling make it a potential candidate for detection of other partially covered substrates.
