Abstract: The stand-off Raman spectroscopy is developed from the microscopic Raman spectroscopy, which is based on the Raman scattering effect. In recent years, the stand-off Raman spectroscopy has become a research hotspot with the improvement of the needs of stand-off explosives detection and planetary detection. The technology improvement of lasers and detectors provides a new method for the study of stand-off Raman spectroscopy. The main research methods of remote Raman spectroscopy and the experimental devices used in this method are introduced. Some new technology the researchers put forward in recent years are summarized, the reasons of the technical methods choosing and their advantages and disadvantages are discussed, so as to explore how to obtain a better result according to the different detection purposes. The future development direction of remote Raman spectroscopy is also discussed.

Key words: spectroscopy, stand-off Raman, Raman spectroscopy, planetary detection, explosives detection
