Abstract: The International Conference on Advanced Optical Diagnostics in
Fluids, Solids and Combustion (VSJ-SPIE04) was successfully held in Tokyo from
December 4th to 7th in 2004 under the co-sponsorship of Visualization Society
of Japan (VSJ) and The International Society for Optical Engineering (SPIE).
Total 66 papers on forefront optical diagnostics and those applications were
presented at the conference and the active and enthusiastic discussions were
made. The results of the conference surely contribute to the future
developments of optical diagnostics in the wide engineering fields.
