ABSTRACT
A floating 3D display with a dihedral corner reflector array (DCRA) is presented to improve space efficiency and eliminate ghost images. Floating displays using a DCRA have the space efficiency problem of having a system thickness equal to the height of the floating image and the problem of a ghost image interrupting the visibility of the floating display. The DCRA is analyzed to find the ghost image region. Based on the analysis, an off-axis integral floating display is placed outside the ghost image region to avoid the ghost image. To increase space efficiency, the optical path is folded using a mirror. In addition, the off-axis integral floating display is used to create a tilt angle for projecting the input image onto the DCRA in a proposed confined and narrow system to observe the complete 3D image. The effectiveness of the system was verified through simulations and experiments.
