Image and hologram fixing method with Sr(x)Ba(1-x)Nb(2)O(6) crystals

We demonstrate a new fixing method with Sr(x)Ba(1-x)Nb(2)O(6) crystals. This is done by inducing ferroelectric domains in the crystal in real time, by a screening mechanism. Images or their holograms can be recorded in small separate locations in the crystal. This crystal pixelization permits the recording of many pictures and their individual readout and erasure.
