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.

    本发明公开了一种挡风玻璃镀膜,包括:第一区域,所述第一区域包括至少一层增透膜,用于透射车内激光雷达出射的光。此部分区域的镀膜是针对LiDAR的出射光的相应波长的增透膜,增透膜可以让挡风玻璃对LiDAR的出射光的反射影响尽可能小,让更多的LiDAR的出射光经过挡风玻璃出射到车外。同时,增透膜可以让LiDAR的接收端受益,能够使得接收端接收到的由视场返回的光信号更强。
