  We propose and demonstrate a method for quantum-state tomography of qudits
encoded in the quantum polarization of $N$-photon states. This is achieved by
distributing $N$ photons nondeterministically into three paths and their
subsequent projection, which for $N=1$ is equivalent to measuring the Stokes
(or Pauli) operators. The statistics of the recorded $N$-fold coincidences
determines the unknown $N$-photon polarization state uniquely. The proposed,
fixed setup manifestly rules out any systematic measurement errors due to
moving components and allows for simple switching between tomography of
different states, which makes it ideal for adaptive tomography schemes.
