1. An optical scanner (100) which comprises:
a mirror (200), provided with a front face (210), essentially planar, and with a rear face (220), said mirror (200) being pivotally mounted about a first pivot axis and being transparent or partially transparent in an area between said front face (210) and up to said rear face (220) or from said front face up to said rear face;
a light source (300) intended to emit an incident light radiation on the front face (210) of the mirror (200), and the mirror (200) being partially transparent from its front face (210) towards its rear face (220) to the light radiation;
the scanner is characterised in that the rear face (220) includes a structuration formed by at least one facet essentially planar and inclined with respect to the front face (210) so that a light radiation, incident on the mirror (200) on the front face (210) side, and transmitted by the at least one facet (220i) undergoes a deflection with respect to an angle of incidence of said light radiation on the front face (210).
