  The small scales of turbulence in a high-Reynolds-number jet ($Re_{\lambda}
\approx 350$) are investigated with a \textmu PIV setup to overcome the optical
limitations of conventional tomographic PIV setups. With the aim of validating
the performances of tomographic long-distance \textmu PIV, analyses are carried
out involving statistical aspects of the small scales of turbulence. The
technique is assessed and the data are bench-marked to be applied to the
analysis of any three dimensional small-scale phenomena in large-scale flow
domains.
