摘要

For Lidar technology that can identify the location of the target substances and measure spatial distribution, theestablishment of that technology is required so that it can comprehensively provide remote measuring hazardous substancesthat cause harm to human bodies, such as toxic substances and combustible substances. Hazardous substances exist in avery wide range of forms, for example, chemical species, physical conditions, and organisms or inorganisms. In addition,substances developed for the purpose of attacking the human body, represented by nerve agents, exhibit their effects by asmall amount. Therefore, in order to realize remote sensing of hazardous substances, it is necessary to apply an excellentmeasurement principle that can respond to the diversity and the detection of trace components of these objects.The Raman effect is a useful phenomenon that enables identification of many individual substances, but the extremelyweak response has led to significant limitations in applicable fields. In this study, we conducted basic experiments for therealization of remote sensing technology of hazardous substances based on the resonance Raman effect.The resonance Raman effect is a phenomenon in which the intensity of Raman scattering light is greatly enhanced byexcitation with light of a wavelength corresponding to the electronic transition energy of the target substance. The presenceof electronic transition energy of substances can be confirmed by observing the ultraviolet absorption spectra. Manyhazardous substances exhibit ultraviolet absorption in the deep ultraviolet wavelength region of 300 nm or less. Therefore,in this study, we constructed a resonance Raman spectrum measuring device capable of wavelength sweeping in the deepultraviolet wavelength range, selected SO2 and NH3, typical corrosive gases, as target substance, and verifiedexperimentally the enhancement of Raman signal intensity by resonance Raman effect.
