Prestressed torsion bending element and a more compact drive for and a method for scanning of light with the use of the bending element

摘要

A drive for the scanning of light, which comprises:a) a support device;b) a bending element on the support device and wherein said torsion parts, which extend along an axis;c) a light reflective scanning mirror on the bending element to the common movement with this;d) includes means for bending of the bending element about the axis in opposite circumferential directions, so that the scanning mirror to oscillate about the axis; ande) integrally with the bending element means for tensioning of the bending element along the axis in a tensioned state, in which the flexible element is bent.
