REMOTE SENSING TECHNOLOGY OF SELF-MADE HAZARDOUS MATERIALS BASED ON RAMAN SPECTROSCOPY

The application of Raman spectroscopy in telemetry of self-made hazardous materials was studied in this paper. The 532 nm laser was used as the light source, and the gating ICCD and the transmission telescope objective enhanced Raman signal were used as the light receiving system to establish the remote Raman experimental system. Using potassium permanganate, nitrate, chlorate and other substances which may be used for Self-made Hazardous Materials as the research samples, the spectra of the three samples were collected, and the remote detection of Self-made Hazardous Materials at the distance of 3-10 m was theoretically realized. The accuracy of the spectral lines collected by the system was verified by comparing the spectral lines of the samples measured by the microscope Raman spectrometer. The practicability of the telemetry capability of the system was proved by comparing the sample lines detected at different working distances.
