説明
We produced an SO2 imager of a low-cost version with the use of digital cameras of consumer use. General configuration and characteristics of the instrument are presented. Calibration with SO2 cells of known column concentration confirmed a comparable absorption coefficient to the device which is previously invented by Mori and Burton (2006). Although simultaneous shooting with two cameras is necessary to overcome the temporal change of an object because of somewhat long exposure time (5 to 10 sec) required, this device operates without external power or control PCs, and thus, is suitable for mobile use. We performed a field test of the instrument at Sakurajima volcano and confirmed its validity as an SO2 imager. However, further improvement of the optical system or a special care with UV scattering in front of a plume is necessary for quantitative applications in a field operation.
