Abstract- In this study, the effect of the light spatial coherency has been experimentally investigated on resolution of the imaging systems. By using the young’s double- slit interference, it is shown, that the spatial coherency of the transmitted light from a rough interface depends on the surface roughness and distance between surface and observation plane. The coherence degree of light rises with increasing distance from rough surface. Also, the effect of the light coherence degree is investigated on the threshold of double-slit imaging resolution, which is taken with an optical microscope. The results show that the resolution increases with decreasing the coherence degree of the light illumination. As a result, the best place to locate the light diffuser in optical microscopes is the minimum distance to the observed sample.
