說明書
In some embodiments, the cover 462 can be tinted with a thin-film neural filter to reduce transmittance of light entering the cover 462. For example, in an embodiment, a lower portion of the cover 462 can be selectively tinted with the thin-film neutral filter to reduce an intensity of visible light seen by the plurality of cameras 432. In this example, transmittance of laser pulses emitted from the LiDAR sensor 430 is not be affected by the tint because only the lower portion of the cover 442 is tinted. In another embodiment, the lower portion of the cover 462 can be tinted with a thin-film graduated neural filter in which the transmittance of visible light can vary along an axis. In yet another embodiment, the whole cover 462 can be treated or coated with a reflective coating such that the components of the enclosure 400 is not visible from an outside vantage point while still being transparent to wavelengths of light receptive to the LiDAR sensor 430 and the plurality of cameras 432. Many variations, such as adding a polarization layer or an anti-reflective layer, are possible and contemplated.
In some embodiments, the enclosure 400 may comprise a frame 434, a ring 436, and a plurality of anchoring posts 438. The frame 434 provides mechanical support for the LiDAR sensor 430 and the plurality of cameras 432. The ring 436 provides mounting points for the cover 462 such that the cover 462 encases and protects the sensor system from environmental elements. The plurality of anchoring posts 438 provides mechanical couplings to secure or mount the enclosure 400 to the autonomous vehicle.
