Abstract
A rain sensor, particularly for a motor vehicle, includes a light-conducting member arranged in an intermediate layer of a glass, and is designed as an optically closed system.
Claims16
A rain sensor for a motor vehicle, the vehicle including a glass, the glass having an intermediate layer, the rain sensor comprising:
- a light-conducting member adapted to be situated in the intermediate layer of the glass, the light-conducting member being an optically closed system that prevents radiation from impinging on a glass-air interface of the glass.
A rain sensor for a motor vehicle, the vehicle including a glass, the glass having an intermediate layer, the rain sensor comprising:
- a light-conducting member adapted to be situated in the intermediate layer of the glass, the light-conducting member being an optically closed system, wherein the light-conducting member is brought out of one end face of the glass.
A rain sensor for a motor vehicle, the vehicle including a glass, the
- glass having an intermediate layer, the rain sensor comprising:
- a light-conducting member adapted to be situated in the intermediate layer of the glass, the light-conducting member being an optically closed system, wherein the light-conducting member includes an optical fiber between a transmitter and a coupling-in location.
A rain sensor for a motor vehicle, the vehicle including a glass, the
- glass having an intermediate layer, the rain sensor comprising:
- a light-conducting member adapted to be situated in the intermediate layer of the glass, the light-conducting member being an optically closed system, wherein the light-conducting member includes an optical fiber between a coupling-out location and a receiver.
A rain sensor for a motor vehicle, the vehicle including a glass, the glass having an intermediate layer, the rain sensor comprising:
- a light-conducting member adapted to be situated in the intermediate layer of the glass, the light-conducting member being an optically closed system, wherein the light-conducting member includes an optical fiber, through which radiation is guided from a transmitter to a coupling-in location, and through which radiation is guided from a coupling-out location to a receiver.
