Abstract
A headlight for a vehicle is described herein. The headlight includes a hybridized device and a controller. The hybridized device includes an array of light emitting devices that illuminate a roadway on which the vehicle is located when operating. The controller is electrically coupled to the hybridized device and, when operating, causes the array of light emitting devices to selectively project a patterned light on to an object on the roadway using the hybridized device and causes a camera to capture an image of the patterned light projected on the object.
Claims17
A headlight for a vehicle comprising:
- a hybridized device comprising:
- a silicon backplane, and
- a monolithic array on the silicon backplane, the monolithic array comprising a plurality of light emitting pixels;
- and
- a controller that is electrically coupled to the hybridized device and is configured to, when operating:
- control the silicon backplane to turn on or off groups of the light emitting pixels to selectively project a patterned light on to an object on a roadway, and
- cause a camera to capture an image of the patterned light projected on the object.
A method of controlling a hybridized device and a camera to detect an object on or near a roadway on which a vehicle is traveling, wherein the hybridized device comprises a silicon backplane and a monolithic array on the silicon backplane, wherein the monolithic array comprises a plurality of light emitting pixels, the method comprising:
- sending a control signal to cause the silicon backplane to turn on or off groups of the light emitting pixels of the hybridized device to selectively project a patterned light on to the object;
- and
- causing a camera to capture an image of the patterned light projected on the object.
