ABSTRACT:
A light deflector for scanning with light from a light source comprises a support body, an oscillation system and a drive means for driving the oscillation system. The oscillation system includes a first movable element and a second movable element having a light deflecting body. The first movable element is resiliently supported by the support body by means of a single first torsion spring. The second movable element is resiliently supported by the first movable element by means of a plurality of second torsion springs located vis-à-vis with the second movable element interposed between them.
