Abstract
An automotive glazing that provides a portal (32) for receiving infrared radiation and an automotive glazing (40, 50) that defines an open pathway for infrared radiation between an infrared camera on one side of the glazing and a camera field of view on the other side of the glazing.
Claims10
A glazing for use in automotive vehicles that include a camera that of a type that is responsive to infrared radiation having a wavelength greater than 8 μm, said glazing comprising:
- a first transparency that defines an outer surface and an inner surface, said inner surface of said first transparency being oppositely disposed on said first transparency from said outer surface, said first transparency having a perimeter edge between said inner surface and said outer surface, said perimeter edge defining the outer perimeter of said first transparency, said first transparency also further defining a portal between said inner surface of said first transparency and said outer surface of said first transparency and inside the perimeter edge of said first transparency;
- and
- a second transparency that defines an outer surface and an inner surface, said inner surface of said second transparency being oppositely disposed on said second transparency from said outer surface of said second transparency, said second transparency being oriented with respect to said first transparency such that said inner surface of said second transparency faces said inner surface of said first transparency layer, at least a portion of said second transparency covering the portal of said first transparency with the material of said second transparency being selected from the group comprising zinc sulfide and polycarbonate.
A glazing for use in automotive vehicles that include a camera that of a type that is responsive to infrared radiation having a wavelength greater than 8 μm, said glazing comprising:
- a first transparency that defines an outer surface and an inner surface, said inner surface of said first transparency being oppositely disposed on said first transparency from said outer surface, said first transparency having a perimeter edge between said inner surface and said outer surface, said perimeter edge defining the outer perimeter of said first transparency wherein the outer perimeter includes a length that forms the top edge of the transparency at times when the transparency is installed in a vehicle;
- and
- a second transparency that defines an outer surface and an inner surface, said inner surface of said second transparency being oppositely disposed on said second transparency from said outer surface of said second transparency, said second transparency being oriented with respect to said first transparency such that said inner surface of said second transparency faces said inner surface of said first transparency, said second transparency having a perimeter edge between said inner surface and said outer surface, said perimeter edge defining the outer perimeter of said second transparency, the outer perimeter includes a length that forms the top edge of the second transparency at times when the second transparency is installed in a vehicle, wherein the top edge of said first transparency and the top edge of said second transparency have a concave contour such that electromagnetic illumination propagates through said concave contour between the outer surface of said second transparency and the outer surface of said first transparency.
