Claim 0:
1. A LIDAR (Light Detection and Ranging) apparatus for a vehicle, comprising:
a light emitter configured to emit laser light;
an angle adjuster configured to adjust an emission angle of the laser light emitted from the light emitter by reflecting the laser light;
a window cover installed to discharge the laser light emitted through the angle adjuster to the outside of the vehicle;
a light receiver configured to receive reflected light introduced into the vehicle through the window cover;
a moisture remover configured to emit far-infrared light using a far-infrared light source to heat the window cover through the angle adjuster;
a sensor configured to sense:
whether moisture has formed on the window cover; and
whether rain or snow is falling; and

a controller configured to control one or more of the angle of the angle adjuster and the intensity of the far-infrared light source of the moisture remover, depending on whether moisture has formed on the window cover, sensed by the sensor,
wherein:
the moisture remover comprises a condensing lens configured to condense the far-infrared light emitted from the far-infrared light source and transmit the far-infrared light to an angle adjusting unit;
when it is determined that moisture is formed on an entire region of the window cover and it is determined that rain or snow is falling, the controller transmits a control signal to the moisture remover and the angle adjuster to heat the entire region of the window cover to a value equal to or greater than a first setting value using the far-infrared light source;
when it is determined that moisture is formed on an entire region of the window cover and it is determined that rain or snow is not falling, the controller transmits a control signal to the moisture remover and the angle adjuster to heat the entire region of the window cover to a value equal to or less than a second setting value using the far-infrared light source; and
when it is determined that moisture is formed on a specific region of the window cover, the controller transmits a control signal to the moisture remover and the angle adjuster to heat only the specific region of the window cover to a value equal to or greater than a third setting value using the far-infrared light source.
