Remote detection of chemicals is highly desirable for homeland security, environmental and NASA planetary exploration programs. Researchers at the University of Hawaii have designed a long range remote chemical detection system that significantly improves upon current capabilities in this field. The technology combines Raman + LIBS spectroscopy into a compact system that is able to perform good quality Raman spectra and LIBS measurements from distances of several hundreds of meters utilizing low laser pulse energy with a detection time of 1 s or less.
