Abstract

The phenomenon of longitudinal spatial coherence of light and conditions of manifestation of this type of coherence in the interference experiments with Michelson interferometer are discussed. Manifestation of longitudinal spatial coherence of light of an extended thermal source at large (in comparison with length of longitudinal spatial coherence) and short lengths oftemporal coherence oflight has been experimentally shown.
