1. An optical transmission and receiving device of an optical detection apparatus of a vehicle, comprising:
at least one optical transmitter for transmitting at least one transmission light beam;
at least one scanning unit at least for changing the beam direction of the at least one transmission light beam; and
at least one optical receiver for receiving at least one reception light beam,
which are arranged relative to one another such that the at least one receiver receives transmission light beams, which have been transmitted by the at least one optical transmitter and are reflected back by an object or obstacle which may be present in a transmission beam path of the at least one transmitter as reception light beams,
wherein the at least one scanning unit comprises:
at least one first beam influencing device for deflecting at least one transmission light beam, which has been radiated into the at least one scanning unit by the at least one transmitter, in a first direction, and
at least one second beam influencing device for changing a beam propagation of the at least one transmission light beam in a second direction,
wherein the at least one second beam influencing device is arranged in the beam path of the at least one transmission light beam downstream of the at least one first beam influencing device,
wherein the first direction and the second direction extend perpendicularly or at an angle with respect to one another,
wherein the at least one second beam influencing device has at least one cylindrical lens for expanding the at least one transmission light beam in the second direction, and
wherein the at least one first beam influencing device has at least one electro-optical light refraction device.
