    Crystals doped with europium ions are known to exhibit ultrasharp hole burning at cryogenic temperatures. In fact, in these materials, the homogeneous widths (hole widths) are extremely narrow (<1 kHz, the narrowest in any solid state) compared to the inhomogeneous absorption widths (〜10 GHz), and the holes are persistent. These findings indicate that the Eu-doped crystals are a candidate for ultrahigh-density frequency-domain optical memory. In addition, due to short bleaching times, even real-time recording of a moving image is possible using a holographic technique. For the first time we succeeded in realizing a holographic motion picture using Eu^<3+> : Y_2SiO_5.

    A method of holographic reconstruction of nuclear magnetic resonance images by making a hologram directly from the NMR signal is described. Since the signal obtained in NMR Fresnel transform technique is given by an equation similar to that of the Fresnel diffraction equation in light, it is possible to reconstruct NMR images by recording the NMR signal as a hologram and using a coherent optical light system. The method, using a liquid crystal-spatial light modulator for displaying holograms will realize a real-time reconstruction of NMR images.

    Holographic television employing acousto-optical spatial light modulator (AOM) can display a true three dimensional image that gives rise not only to binocular parallax and convergence but also the focal accommodation effects. Since the system includes mechanical scanning, it is considered as a temporary system until static display comes out. However, it is very difficult to build static system with currently available spatial light modulators. Therefore, some researches to modify AOM display are also conducted. This paper gives a review and research trends on AOM display.

    A three dimensional (3D) video system is utilized 3D Grating Image technology. The 3D video image from the system consists of many parallax images, and an observer can be shown the 3D image in real time without glasses. The system is composed of an LCD panel and grating array. Therefore the system has simple structure and wide viewing area.
