Abstract

Doped liquid crystals, as super-fast refresh holographic media, are very useful in holographic 3D video display because of their extraordinarily high optical nonlinearity arising from laser-induced director axis reorientation. We obtained real-time dynamic holographic display with holographic response time under an order of a microsecond using the super-fast-response liquid crystal films. The hologram formation time and self-erasable time can both reach ~ 1 ms in this film. Holographic video display was realized using them without any cross talk between the holograms. In this paper, the mechanism of real-time hologram recording and self-erasure will be presented based on light-induced liquid crystal molecular reorientation in the films.
