摘要
Wide field of view combiners for head-up displays are reviewed and our originally developed combiner using Fresnel reflector that acts both as a concave reflector for reflected light and a flat plate for transmitted light has been introduced. Main issue of ghost image derived from diffraction and refraction is eliminated by Fresnel pattern with variable pitch, sandwiched by the materials with the same refraction index.
