We discuss a recently proposed scheme for the reconstruction of the quantum state of a one-mode traveling light wave. In the cascaded homodyning scheme the balanced and unbalanced principles of homodyning are combined. We present here a derivation of the universal sampling function by inverting the Radon transformation occurring in the second stage of the setup. The sampling function possesses a simple structure, which is independent of the location of the phase-space point. This latter property makes it a promising tool for detecting nonclassical oscillations in quasiprobability functions.
