  The CBELSA/TAPS experiment with a longitudinally or transversely polarized
target and an energy tagged, linearly or circularly polarized photon beam
allows the measurement of a large set of polarization observables. Due to its
good energy resolution and high detection efficiency for photons, as well as
the nearly complete solid angle coverage, it is ideally suited for the
measurement of neutral mesons decaying into photons. Preliminary results for
the target asymmetry T, the recoil polarization P, and the double polarization
observable H are shown for \pi^0 and \eta photoproduction off the proton.
