We report on the experimental observation of interference pattern of a distributed double-slit, consisting of a single-slit and a wire spatially separated, illuminated by two beams from a pseudothermal light source, in Hanbury Brown and Twiss–like configuration. The interference pattern is obtained performing a classical correlation with the intensities of the light beams scattered by each part of the double-slit. A theoretical analysis confirms our experimental results, showing that classical correlations can also mimic non-local properties analogue to those using twin photons for quantum images.
