Abstract

New technologies to measure hazardous substances quickly and safely are always required in a wide range of fields. However, the physical properties and the physical states of hazardous substances generated by such as: air pollution, volcanic activity, CBRNE disasters are assumed to vary. For this reason, there is still no device can measure hazardous substances comprehensively. To solve this problem, we have been focusing on the research and development of remote sensing device that is highly sensitive and applicable to various hazardous substances by using resonance Raman effect. We selected air pollutants sulfur dioxide and ammonia as target gases for remote sensing. Three sigma limits for sulfur dioxide and ammonia in this measurement were 3 ppb and 15 ppb at 100 m.
