Claim 12:
13. A method for generating a setpoint field of view for an emitter device of an optical detection apparatus of a motor vehicle, wherein the emitter device comprises a light source for emitting a light beam and a guiding unit, the method comprising:
emitting the light beam onto the guiding unit by the light source; and
guiding the emitted light beam at different scanning angles by means of the guiding unit,
wherein at least two separately drivable emitter elements for emitting the light beam are provided for the light source, the emitter elements emitting the light beam onto the guiding unit at angles of incidence corresponding to predetermined setpoint values of the scanning angle to generate a predetermined setpoint field of view of the emitter device,
wherein the guiding unit comprises a tiltable mirror, which is configured in order to guide the light beam emitted by the respective emitter element at the setpoint value for the scanning angle which corresponds to the respective angle of incidence, and
wherein the angles of incidence of the light beam, which are provided by the emitter elements, are predetermined as a function of tilt angles of the tiltable mirror r,
wherein the tiltable mirror has a characteristic transfer function, by which a distortion of an actual field of view generated by the tiltable mirror with respect to the setpoint field of view is described as a function of tilt angles of the tiltable mirror, and
the emitter elements are driven via a drive strategy so that an inverse of the characteristic transfer function is provided by the angles of incidence.
