Abstract
The invention relates to electro-optical media which make it possible to record holograms in real time. It consists in using a lamina of a selected material such as bismuth-silicon oxide, this lamina being subjected to a transverse electric field perpendicular to the fringes of the hologram to be inscribed, and in illuminating this lamina with a light beam which is not coherent with the two object and reference beams which interfere within this lamina.
