Abstract

The invention discloses a windshield coating film which comprises a first area, and the first area comprises at least one layer of antireflection film used for transmitting light emitted by a laser radar in a vehicle. The coating film in the area is an antireflection film aiming at the corresponding wavelength of the emergent light of the LiDAR, and the antireflection film can enable the reflection influence of the windshield on the emergent light of the LiDAR to be as small as possible, so that more emergent light of the LiDAR is emitted out of the vehicle through the windshield. And meanwhile, the antireflection film can benefit the receiving end of the LiDAR, so that the optical signal returned by the field of view and received by the receiving end is stronger.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of optical coatings, in particular to a windshield coating. Background technique [0002] At present, the rapid development of intelligent driving technology has greatly promoted the research of various environmental perception sensors. Vehicle-mounted laser radar (LiDAR) occupies an important position in the intelligent driving environment perception system because of its advantages such as accurate acquisition of three-dimensional information of the target, high resolution, strong anti-interference ability, wide detection range, and nearly all-weather work. At present, the more mainstream vehicle-mounted LiDAR is placed outside the vehicle, and its outgoing light is not affected by factors such as windshield reflection and refraction, and its performance is better. However, because LiDAR is placed outside the vehicle, on the one hand, it is easily affected by harsh environmental fact...
