1. An optical scanner which comprises:
an optical source capable of emitting a main optical beam;
at least two elementary scanners, referred to as first and second scanners respectively, and which comprise:
a first and a second beam provided, respectively, with a first and a second movable part on the one hand, and a first and a second fixed parts on the other hand;
a first and a second actuator arranged to deform, respectively, the first and the second movable parts; and
a first and a second optical phased array disposed on or in the first and the second movable parts, respectively, and at which the main optical beam is partly extracted, as a first and a second beam, respectively;
the first and second scanners being arranged to scan, along a first and a second direction, by means of the first and second beams, respectively, a first and a second surface, the second surface being of smaller extent than the first surface and included in the first surface.
