We have developed a head-up display (HUD) using a holographic combiner. A HUD superimposes information in front of the driver. The HUD must be unaffected by sunlight and should be small. A holographic combiner eliminates the VFD wash-out, and compensates for the distortion of concave mirror. The size of unit is reduced by folding the optical path. The image distance is extended to 1.2 m by using a powered element. The dimensions of the HUD unit is 155 X 135 X 77 mm, and the thickness of the optical unit is 40 mm.
