BEAM DEFLECTION UNIT FOR INFLUENCING AN ANGLE OF A LIGHT BEAM COUPLED OUT OF THE BEAM DEFLECTION UNIT AND METHOD FOR OPERATING A BEAM DEFLECTION UNIT

摘要

The invention relates to a beam deflection unit (100) for influencing an angle of a light beam coupled out of the beam deflection unit (100), wherein the beam deflection unit (104) firstly has a Bragg deflector unit (109) which comprises a first (151) and a second (160) Bragg mirror, which are arranged opposite each other and between which a cavity is formed. The beam deflection unit (100) also has a light guide groove (154), which is formed in the first (151) and/or second (163) Bragg mirror, wherein the light guide groove (154) adjoins the cavity. Finally, the beam deflection unit (100) has at least one drive element (160) arranged on the first Bragg mirror (151) for moving at least one sub-region of the first Bragg mirror (151) relative to the second Bragg mirror (163), in order to influence an angle of a light beam coupled out of the beam deflection unit (15) during operation of the beam deflection unit (100).
