Laser-induced breakdown spectroscopy (LIBS) is well known for its feature of remote detection. In this review, the development of remote detection based on LIBS is presented. Three kinds of remote LIBS configurations and their characteristics have been illustrated. Owing to an inferior efficiency and intensity of spectral signals collected in a remote distance, different methods have been studied to enhance signals. This review briefly summarized the advanced enhancement approaches for remote LIBS, which further improves the capabilities of LIBS for real-time and in situ measurement. Furthermore, the recent development and application of remote LIBS in a variety of fields have been presented. The potential of LIBS in remote detection and its existing problems have also been discussed.
