Knowing the underlying number and structure of occupied modes of a light field plays a crucial role in minimizing loss and decoherence of quantum information. Typically, full characterization of the mode structure involves a series of several separate measurements in spatial, temporal, frequency and polarization domains. Here we present a simple method to reconstruct the mode distribution of multi-mode classical and non-classical optical fields using a single measurement of higher-order photon number correlation functions. We experimentally demonstrate reconstruction of up to three modes with excellent agreement and study the robustness of our method in experimentally realizable regimes.
