Abstract:
A microscope comprising:a laser generating a coherent optical wave,means to split said coherent optical wave into an illuminating wave which illuminates the observed object, and a reference wave, distinct from the illuminating wave, and which does not reach the observed object,means to sample and digitize the optical intensity received on a receiving surface on which an interference pattern is formed by the reference wave and the wave emanating from said object,means to determine, at each sampled point of said receiving surface, the phase and amplitude of the wave emanating from the observed object and reaching said receiving surface,a microscope objective focused on the observed part of said object, which forms an enlarged intermediate image of the plane of said object on which it is focused,means to superimpose the wave emanating from said object and having passed through said microscope objective, to the reference wave which does not pass through said microscope objective,optical devices that modify the wave emanating from said object in such a way that a plane wave emanating from the observed object and entering said microscope objective has a point image on the receiving surface,a diaphragm which spatially filters said enlarged image formed by said microscope objective.
