abstract = {A laser-based technique for measuring instantaneous
three-dimensional species concentration distributions in
turbulent flows is presented. The laser beam from a single
laser is formed into two crossed light sheets that
illuminate the area of interest. The laser-induced
fluorescence (LIF) signal emitted from excited species
within both planes is detected with a single camera via a
mirror arrangement. Image processing enables the
reconstruction of the three-dimensional data set in close
proximity to the cutting line of the two light sheets.
Three-dimensional intensity gradients are computed and
compared to the two-dimensional projections obtained from
the two directly observed planes. Volume visualization by
digital image processing gives unique insight into the
three-dimensional structures within the turbulent processes.
We apply this technique to measurements of toluene-LIF in a
turbulent, non-reactive mixing process of toluene and air
and to hydroxyl (OH) LIF in a turbulent methane-air flame
upon excitation at 248 nm with a tunable KrF excimer laser.},
