Abstract: A microscope is disclosed which determines a complex three-dimensional representation of an object based on a series of recordings of the light wave diffracted by the object, wherein the direction of the wave lighting of the object varies between two succesive recordings. The diffracted wave interferes with a reference wave on a receiving surface and a frequency representation of the diffracted wave is computed from interference patterns received on the receiving surface. A plurality of frequency representations of diffracted waves are then superimposed yielding a frequency representation of the object. The phase of each frequency representation of a diffracted wave is shifted in order to compensate for variations of the phase difference between the reference wave and the wave lighting of the object.

Abstract: The invention concerns a microscope comprising an optical part for generating interference figures between a reference light wave and a light wave diffracted by the observed object, sensors for digitising these interference figures, actuators for operating the optical system, and a computer for receiving the digitised interference figures, controlling the actuators, and provided with a memory and computing means for computing the three dimensional images from the interference figures, based on a principle analogous to holography. The optical part enables the recording on a sensing surface (116) interference figures generated by a reference beam (Fr) and a beam (Fe) passing through a sample (109). The interference figures can differ from one another by the reference wave phase controlled by the piezoelectric actuator (120) or the spatial distribution of the illuminating beam controlled by the positioning device (106). This microscope can be used in biology or metrology.
