An algorithm for the tomographic reconstruction of the
individual moments of the probaility density functions
describing the local transmittance of radiation through
a turbulent flow field is advanced. The new method,
which is based on Fourier inversion, is applicable to
asymmetric (as well as, to axisymmetric) flows. The
validity of the method is examined by comparing
reconstructed moments of the local probability functions
in a buoyant propene/air flame and an ethene/air jet
flame to the corresponding values obtained from optical
