Abstract: A holographic optical memory is disclosed which utilizes an erasable storage medium such as manganese bismuth. Light from a laser is directed to an illumination hologram, from which a diffracted beam illuminates an object. Light from the object is condensed on a small area of the storage medium. The undiffracted light passing through the illumination hologram is directed as a reference beam to the storage medium, where it interacts with the object beam to record a hologram of the object on the storage medium.

Abstract: In a display device a modulator structure may be formed by disposing on a surface of the back wall a plurality of first control electrodes. A modulator member having a smoothly continuous surface has disposed thereon a plurality of second control electrodes. The surfaces of the back wall and the top member having the electrodes thereon are joined together to form opposing pairs of control electrodes.

Abstract: In a display device having an evacuated envelope, an electron beam guide and an electron generating means for generating beams of electrons, a modulator structure on which is disposed a plurality of control electrodes may be formed by interconnecting selected ones of the control electrodes which operate at a common potential. This interconnected electrode structure decreases the number of control electrodes which extend from the evacuated envelope. The electron generating means is shielded from the interconnected electrode structure to prevent perturbation of the generated electron beams.
