| Abstract: | Objective To explore the method for analysis of pyrotechnic. Methods S, Ba（NO3）2, KC10~ and KC104 were ana- lyzed by Laser Confocal Raman Spectroscopy. Results Different substances have different Raman bands. Conclusion Different compo- nents of pyrotechnic can be identified by their characteristic l~aman spectra. The distributing information also can be obtained by imaging technique. The Laser Confocal Raman Spectroscopy method is a non-invasive, non-destructive analytical method allowing samples to be examined without any preparation. |
