Abstract: The present invention relates to a method comprising reception of an incident electromagnetic wave (9) by a diffractive element (2) and conversion of this incident electromagnetic wave (9) into a diffracted electromagnetic wave (10) by the diffractive element (2); reception of the diffracted electromagnetic wave (10) by a matrix-array sensor (4) comprising a matrix-array of pixels that are aligned along one or two axes of pixel alignment (13, 14). The method comprises a plurality of acquisitions, by the matrix-array sensor (4), of a signal of the diffracted electromagnetic wave (10) corresponding to a plurality of relative positions between the diffractive element (2) and the matrix-array sensor (4). The invention also relates to a device (1) implementing this method.

Abstract: A system for structural analysis of an object, including a device for generating an input light beam arranged so as to cause the input beam generated to interact with at least one portion of the object, and a device for receiving the output light beam resulting from the interaction between the input beam and the object. In this system, the receiving device include a wavefront analyzer arranged so as to measure the electromagnetic field of the wave of the output beam received, and the generating device has a spatial coherence adapted to that of the receiving device. A structural analysis method implementing such a system is presented.
