Brief description of embodiments of a transfer hologram has a wide field of vision on its real orthoscopic image and the resulting hologram

摘要

The invention is a process which consists in recording a transfer hologram 3 on a holographic recording material whose surface has a three-dimensional shape having at least a curvature that is reentrant. / p & & p & the concavity of the curvature is, during the transfer, turned towards part or all of the real image pseudoscopic of the hologram to be transferred 1. And, on playback, it is turned towards the observer o ≦ / p & & p & thus, the observer o, moving along at least one plane p, may be the most prominent portions of the real orthoscopic image iro of the transfer hologram 3 through the hologram transferred 1, on a viewing angle beta, which may reach 180 degrees.
