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.
