A driver's night view assistance system has been put into practical use. The night view assistance system helps drivers to see farther down the road than low beam headlamps by illuminating the road scene with an infrared projector. We have developed an infrared projector by using a projector type headlamp. Infrared is produced by shielding visible light at a multiple-layer film of Silicon (Si) and Silicon Dioxide (SiO2) which is deposited alternately on a condenser lens surface. The principle of the multiple-layer film and the infrared projector's structure are reported in this paper.
