Emitter device for an optical detection apparatus, optical detection apparatus, motor vehicle and method

Abstract

The invention relates to a emitter device () for an optical detection apparatus () of a motor vehicle (), which is designed to scan a surrounding region () of the motor vehicle () by means of a light beam (), and which comprises a light source () for emitting the light beam () and a deflection unit (), wherein the deflection unit () is designed to deflect the light beam () emitted onto the deflection unit () by the light source () at different scanning angles (α), wherein the deflection unit () comprises a freeform mirror (). The freeform mirror () comprises at least two surface elements () having different angles of inclination () and is designed to reflect the light beam () in order to generate a predetermined setpoint field of view () of the emitter device () at predetermined setpoint values (−α3, −α2, −α1, α0, +α1, +α2, +α3) for the scanning angle (α), said setpoint values corresponding to the angles of inclination (). The invention additionally relates to an optical detection apparatus (), a motor vehicle () comprising at least one optical detection apparatus (), and to a method for generating a setpoint field of view () for an emitter device () of an optical detection apparatus () of a motor vehicle ().
