Abstract

A heating cover for a LiDAR sensor includes a plastic cover layer and a heating film attached to a back surface of the plastic cover layer. In the heating film, an indium tin oxide (ITO) thin film layer is formed on a polyethylene terephthalate (PET) film. Respective line electrodes are arranged along both long sides on the ITO thin film layer.

Claims (21)

1 . A heating cover for a Light Detection and Ranging (LiDAR) sensor, the heating cover comprising:

a plastic cover layer; and

a heating film attached to a back surface of the plastic cover layer, wherein the heating film is a polyethylene terephthalate (PET) film on which an indium tin oxide (ITO) thin film layer is formed, and wherein respective line electrodes are arranged along both long sides on the ITO thin film layer,

wherein the ITO thin film layer is divided in a direction parallel to a short side thereof.

2 . The heating cover of claim 1 , wherein the line electrodes in a pair are arranged in parallel.

3 . The heating cover of claim 2 , wherein a sheet resistance of the ITO thin film layer has a range of 50 to 70Ω.

4 . The heating cover of claim 3 , wherein a transmittance of the ITO thin film layer is at least 70% at 905±60 nm.

5 . The heating cover of claim 3 , wherein the line electrodes have a thickness of 15 to 20 μm.

6 . The heating cover of claim 2 , further comprising a first low-reflective layer coated on a front surface of the plastic cover layer.

7 . The heating cover of claim 6 , further comprising a second low-reflective layer coated on a back surface of the PET film.

8 . The heating cover of claim 7 , wherein each of the first low-reflective layer and the second low-reflective layer is a multilayer film composed of a ZrO 2 thin film layer and a SiO 2 thin film layer.

9 . The heating cover of claim 1 , wherein the ITO thin film layer is divided into four or more regions.

10 . The heating cover of claim 9 , wherein the ITO thin film layer is divided into five regions.

11 . A method of manufacturing a heating cover for a Light Detection and Ranging (LiDAR) sensor, the method comprising:

forming an indium tin oxide (ITO) thin film layer on a polyethylene terephthalate (PET) film to prepare a heating film; and

attaching the heating film to a back surface of a plastic cover layer, wherein respective line electrodes are arranged along both long sides on the ITO thin film layer,

wherein the ITO thin film layer is divided in a direction parallel to a short side thereof.

12 . The method of claim 11 , wherein the line electrodes in a pair are arranged in parallel.

13 . The method of claim 11 , further comprising:

forming a first low-reflective layer on a front surface of the plastic cover layer; and

forming a second low-reflective layer on a back surface of the PET film.
