APPARATUS COMPRISING AN ELECTRICALLY CONTROLLABLE REFLECTION DEVICE FOR DEFLECTING A RADIATION BEAM |
摘要 |
An apparatus, for example for recording and/or reading information on an optical record (2), comprises an electrically controllable reflection device (7) which deflects a radiation beam (3) in a direction which is determined by an electric control signal, which causes the pivotable reflection element to pivot about a pivoting axis (11) to a limited extent. To improve the frequency response and rigidity of the reflection device, the base of the reflection element is an optical body which comprises a plurality of separate portions (13, 14) and the reflecting surface (12) of the reflection element is interposed between separate portions of the optical body. |
