Abstract: An object detection system and method for a vehicle headlight include a visible light emitter and an object sensing subsystem having an infrared line emitter for emitting infrared detection radiation and an infrared line detector. An optical subsystem receives the visible light and directs it into an external region to illuminate the external region and receives the infrared detection radiation and directs it onto an object in the external region. The optical subsystem includes a partially reflective element optically between the infrared line emitter and the external region and optically between the object sensing subsystem and the external region. The partially reflective element is configured to pass one of the infrared detection radiation and the visible light and to reflect the other of the infrared detection radiation and the visible light, such that the object sensing subsystem senses the object in a line-scan-gated mode.

Abstract: An example system includes an infrared emitter to output infrared light towards a target, where the infrared light reflects from the target to produce reflected infrared light, and a detector to receive the reflected infrared light and to provide a signal based on the reflected infrared light. The system also includes a lighting system that includes a light emitter to output visible light, a mirror configured (i) to allow the visible light to pass through the mirror and to reflect the reflected infrared light onto the detector, or (ii) to allow the reflected infrared light to pass through the mirror and onto the detector and to reflect the visible light, and one or more optical elements configured to affect the visible light and the reflected infrared light.

Abstract: An example system includes a light source coated with a phosphor layer, a laser emitter to output a laser beam, and a controller to control a direction of the laser beam so that the laser beam hits a location on the phosphor layer. The laser beam excites the location on the phosphor layer to produce a spotlight at the location.
