  We show that it is possible to build effective matter density power spectra
in tomographic cosmic shear observations that exhibit the Baryonic Acoustic
Oscillations (BAO) features once a nulling transformation has been applied to
the data. The precision with which the amplitude and position of these features
can be reconstructed is quantified in terms of sky coverage, intrinsic shape
noise, median source redshift and number density of sources. BAO detection in
Euclid or LSST like wide surveys will be possible with a modest signal-to-noise
ratio. It would improve dramatically for slightly deeper surveys.
