This video shows a Raman spectrometer mounted on a robotic platform making observations of titanium oxide from a distance of > 1 m.
Raman spectroscopy can be used to identify almost any molecular compound, however, the scattering process is weak making standoff observations of greater than a few 10s of centimetres challenging.
ISI’s range of HES spectrometers seeks to resolve this problem. In this video, observations are made of TiO2 from a robotic platform. This system could be converted to search for a variety of hazardous materials from explosive to polluting compounds within extreme environments such as radiation or high-temperature.
