Abstract:
A dual output headlight system includes a projection system having a laser light source to emit incoherent light. The projection system also has a partitioned display surface including a headlight display section and a selectively active augmented display section. The partitioned display surface is positioned in a first path of the incoherent light from the laser light source and to generate a display output. The dual output headlight system also includes an optical splitter positioned in a second path of the display output to split the display output into a headlight illumination output and a graphical output.
