... as the mineral content of the sample, or the presence of more complex biomarkers. For example, in previous studies, Raman spectroscopy has been used to detect a pigment known as scytonemin, which is produced by a microorganism known as cyanobacteria...
...item. Finally, among the LIDAR techniques, particularly promising techniques could be based on Fluorescence and Raman spectroscopy, although the latter operates with a signal relatively too weak to be realistically applicable for satellite monitoring...
