The financial support of the Spanish Ministry of Science and Innovation (MICINN), grant TEC2008-04105 is acknowledged. We are indebted to Maria Paz Hern´andez-Garay, Ana Manzanares and Oscar Martínez-Matos for their very valuable support and suggestions.We present a revisited study of the Thompson-Wolf experiment earlier developed in 1957 with the aim to characterize the degree of spatial coherent of a luminous source. We develop further experiments by using laser sources under various modal regimes. We analyze the experimental results.engjournal articlehttp://dx.doi.org/10.2971/jeos.2010.10051shttp://www.jeos.org/open access535CoherenceInterferenceLightBeamÓptica (Física)2209.19 Óptica Física
