    "abstract": "Complementarity is usually considered as a phenomenon of microscopic systems.\nIn this paper we report an experimental observation of complementarity in the\ncorrelated double-slit interference with a pseudothermal light source. The\nthermal light beam is divided into test and reference beams which are\ncorrelated with each other. The double-slit is set in the test arm, and the\ninterference pattern can be observed in the intensity correlation between the\ntwo arms. The experimental results show that the disappearance of interference\nfringe depends on whether which-path information is gained through the\nreference arm. The experiment therefore witnesses the complementarity occurring\nin a macroscopic system.",
