1. A LiDAR apparatus comprising:
a light transmitter which emits and sweeps light beams in a scanning direction;
an optical window which is disposed in an opening of a housing in which the light transmitter is disposed and permits the light beams, as emitted from the light transmitter, to pass therethrough; and
a heating wire which is configured to supply heat to the optical window,
wherein
the heating wire has at least one section that is located at equal intervals away from two of a plurality of beam center lines, and the at least one section extends parallel to the two of a the plurality of beam center lines which are arranged adjacent each other, and
each of the plurality of beam center lines is a line extending in the scanning direction through centers of a plurality of beam transmitting regions of the optical window through which the light beams pass.
