A multi-functional single-photon detector was demonstrated to resolve photon states by multiple superconductor single photon detectors (SSPDs) system with improved readout settings. The photon number and space distribution were resolved simultaneously by the presented system, which inherits the merits of SSPD, such as wide-response band, high repetition rate and working stability. Experimentally, four photons were resolved and the photon distribution over three pixels was figured out according to the amplitudes of output pulses at the telecommunication wavelength. The extension of this proposal to incorporate more elements for resolving more photons and revealing photons spatial distribution over larger scale is also discussed.
