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.
