[3DSAp2/3Dp2-9] See-Through Aerial Concave Display by Use of Fresnel Lens and AIRR with Polarization Modulation
aerial display, polarization modulation, retro-reflector
This paper proposes an optical system for see-through aerial concave display. Due to aberration of Fresnel lens, a 2D image on a flat-panel display is converted to a convex image. Then, the convex image is converted to an aerial concave image with AIRR (Aerial Imaging by Retro-Reflection) in see-through structure.
