Abstract
Official abstract text for this publication.
A LIDAR apparatus is disclosed. A LIDAR apparatus according to an embodiment of the present invention comprises a cover window which covers a transmission path and reception path of laser light and is disposed in the same, and comprises a heating unit which covers a surface of the cover window and is disposed at the same, and a heating control unit connected to the heating unit to control the same.
First claim
Opening claim text (preview).
1 . A LIDAR apparatus which comprises a cover window which covers a transmission path and reception path of laser light and is disposed in the same, the LIDAR apparatus comprising: a heating unit which covers a surface of the cover window and is disposed at the same; and a heating control unit connected to the heating unit to control the heating unit. 2 . The LIDAR apparatus of claim 1 , wherein the heating unit is formed of a heating film. 3 . The LIDAR apparatus of claim 2 , wherein the heating film is formed to be transparent. 4 . The LIDAR apparatus of claim 3 , wherein the heating film is disposed to have an area corresponding to the area of one surface of the cover window. 5 . The LIDAR apparatus of claim 1 , further comprising: a temperature measuring unit which is coupled to the cover window or disposed adjacent to the cover window to measure the temperature and transmit the same to the heating control unit. 6 . The LIDAR apparatus of claim 1 , further comprising: a resistor unit which is disposed to cover the other surface of the cover window; and a detection unit for detecting whether the cover window is damaged by detecting a change in resistance of the resistor unit. 7 . The LIDAR apparatus of claim 6 , wherein the resistor unit has a matrix structure. 8 . The LIDAR apparatus of claim 6 , wherein the resistor unit is formed of a transparent resistance film. 9 . The LIDAR apparatus of claim 6 , wherein the cover window is coupled to a housing that protects an optical system for transmitting and receiving the laser light from an external environment, and wherein the heating unit is disposed on a surface located inside the housing among both surfaces of the cover window, and the resistor unit is disposed on a surface located outside the housing among both surfaces of the cover window. 10 . A LIDAR apparatus, comprising: a cover window which covers a transmission path and reception path of laser light and is disposed in the same, and further comprising: a resistor unit which is disposed to cover a surface of the cover window; and a detection unit for detecting whether the cover window is damaged by detecting a change in resistance of the resistor unit. 11 . The LIDAR apparatus of claim 10 , wherein the resistor unit has a matrix structure. 12 . The LIDAR apparatus of claim 10 , wherein the resistor unit is formed of a transparent resistance film.
