Paper Abstract

Various kinds of optical diagnosis for atmospheric pressure non-thermal plasma which the authors have examined experimentally, are explained. They are LIF of OH (248nm excitation), NO (226nm), TARIF of O (225nm), Sclieren image, ozone profile observation by the laser absorption, spectrum analysis of the plasma including NO-γ emission, and streamer propagation. The last can be controlled by the gated IICCD camera but others are controlled by the laser emission which makes possible to observe the time change after the plasma. Those data propose the O generation in the streamer region which produces the ozone or VOCs oxidation. O radical is now a very important parameter as the VOCs decomposition, especially, related with the catalyst effect.
