  • Atomic beam pattern forming method using atomic beam holography
    Patent number: 5834769
    Abstract: A hologram is made up from a one-dimensional or two-dimensional slit array, each slit being formed with an electrode pair or electric wire for generating an electric field or magnetic field within the slit. These electric fields or magnetic fields are each set for each slit so as to confer upon an atomic beam passing through the slits a phase shift corresponding to the target hologram reproduced image, thereby allowing the target hologram image to be easily reproduced by directing the atomic beam perpendicular to the hologram surface.
