摘要： This invention concerns electrically controlled optical deflectors, and more specifically an optical deflector comprising a mirror forming part of an assembly which cam move in relation to a fixed base, the pivotal movements of this assembly being controlled by an electrodynamic motor with a winding through which a variable current passes, and which is situated inside a predetermined magnetic field, the mechanical connection between the movable assembly and the fixed base being provided by a prismatic elastic component.This invention applies in particular to the construction of reading heads to direct an optical beam on to a videodisc track.

摘要： The optical head in the recording-reading device of a data carrier comprises a semiconductor laser source. A lens makes it possible to focus the beam from this source on to the data carrier via a reflecting or deviating mirror. According to the invention the rotation axis of this mirror is in the plane of the entrance pupil and of the focus of the focusing lens.
