Abstract: A scanner provided with a plurality of elementary scanners, especially two elementary scanners, referred to as a first and second scanner respectively. In particular, the first scanner and the second scanner are arranged to scan, each with an optical beam, respectively, a first surface and a second surface included in the first surface and of a smaller extent than the latter.

Abstract: A scanner is provided with a plurality of elementary scanners each able to scan a different surface by means of a light beam. Each elementary scanner comprises a beam, for example a vibrating beam, on or in which a phase-controlled array is formed, intended to extract, at a face of the beam, a light beam able to be emitted by a light source. At least one beam of one of the elementary scanners, referred to as the first scanner, has, at rest, a deflection different from that of the beams of the other elementary scanners. This arrangement enables the first scanner to scan a surface, referred to the first surface, different from that scanned by the other elementary scanners. The optical scanner according to the present invention makes it possible to cover a relatively large surface while keeping appreciable compactness.

Abstract: The present invention relates to a scanner provided with a vibratory beam on or in which is formed a phased array intended to extract according to either one of two parallel faces of the beam a light radiation that could be emitted by a light source.

Abstract: A detection device for a coherent imaging system includes a detector comprising a matrix array of pixels, each pixel comprising a photodetector component having a photosensitive surface, the detector being designed to be illuminated by a coherent beam, called the image beam consisting of grains of light called speckle grains, a matrix array of transmissive deflecting elements configured to be individually orientable by means of an electrical signal, so as to deflect a fraction of the image beam incident on the group, and thus modify the spatial distribution of the speckle grains in the plane of the photosensitive surface, each group of one or more pixels further comprising a feedback loop associated with the deflecting element and configured to actuate the deflecting element so as to optimize the signal-to-noise ratio from the light detected by the one or more photodetector components of the group of pixels, the feedback loop comprising a feedback circuit.

Abstract: The invention relates to a method for transferring at least one layer of material, comprising: producing first and second separating layers (108, 110), one against the other, on a first substrate (104); producing the layer to be transferred on the second separating layer (110); securing the layer to be transferred to a second substrate (106), forming a stack of different materials; and performing mechanical separation at the interface between the separating layers; in which the materials of the stack are such that the interface between the first and second separating layers has the weakest adhesion force, and the method comprises a step reducing an initial adhesion force of the interface between the first and second separating layers.
