Abstract ： It is well known that the indistinguishability of particles causes interference. We give a "which way" experiment of two-photon interference marked with polarization. The result shows that the greater the distinguishability of the path by which two-photon passes, the lower the fringe visibility will be, and this phenomenon will disappear when the path becomes completely distinguishable.
