Keywords:hologram, conical, wide viewing zone

We have been studying the non-planar hologram to realize sufficient viewing zone and field of view in the holographic 3D display. Before, we reported enlarged viewing zone by a trigonal pyramid hologram. However, the discontinuity between adjacent faces matters. In this study, a conical hologram was fabricated to overcome that. As a result, horizontal viewing zone of 180 deg. and vertical viewing zone of more than 60 deg. were experimentally achieved.
