DOUBLE-GLAZED WINDOW WITH INTEGRATED LIGHT SENSOR AND HOLOGRAPHIC OPTICAL ELEMENT Russian patent published in 2022 - IPC B32B17/10 

FIELD: automotive industry.

SUBSTANCE: group of inventions relates to a double-glazed window for a vehicle, to the method for its manufacture, as well as to its use in a vehicle. A double-glazed unit for a vehicle with an integrated light sensor includes an outer sheet of glass and an inner sheet of glass connected to each other by at least one thermoplastic intermediate layer. The double-glazed unit includes at least one light sensor having at least one light-sensitive surface located between the outer sheet of glass and the inner sheet of glass. The photosensitive surface faces the outer sheet of glass. The holographic optical element is located between the photosensitive surface and the outer sheet of glass. The holographic optical element is made in the form of a hologram, depending on the incidence angle of diffraction of incident light (L, R).

EFFECT: group of inventions provides an improved double-glazed window with an integrated light sensor, which can be manufactured using the simplest and most cost-effective method and in which the light sensor has a flat structure.
