Achromatic and distortion-suppressed floating image display system using SCD

In this paper, a floating 3D display system that consists of an autostereoscopic display and a symmetric cemented doublet (SCD) is demonstrated. 3D image is generated by the autostereoscopic display and it floats into a free space by the use of the SCD. Furthermore, SCD is designed to correct the chromatic aberration and distortion of the floating system. To confirm the feasibility of the proposed system, simulations and experiments are performed, and the results are comparatively discussed with those of the conventional system.
