Abstract
A LiDAR apparatus includes a light transmitter, an optical window, and a heating wire. The light transmitter emits and sweeps light in a predetermined scanning direction. The optical window is disposed in an opening of a housing in which the light transmitter is installed and permits light beams, as outputted from the light transmitter, to pass therethrough. The heating wire works to supply heat to the optical window. The heating wire has at least one section which is located at equal intervals away from and extends parallel to two of a plurality of beam center lines which are arranged adjacent each other. Each of the 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.
