    摘要： A security device including a surface relief microstructure which, in response to incident radiation, replays a hologram viewable within a viewing zone, the hologram including at least a first holographic image element in an image plane spaced from the surface of the microstructure. The device exhibits at least one further image in a plane spaced from the image plane of the first holographic element. On tilting the device, the first holographic image element exhibits apparent movement relative to the further image, which when expressed in radians, a rate of parallax movement per radian equals the spacing between phones and the product of the rate of movement and the included angle of the viewing zone defining a distance at least 20% of the dimension of the device in the direction of movement of the first holographic image element.

    摘要： A method of recording a surface relief microstructure in a record medium includes: i) causing a coherent reconstruction or replay beam to impinge on a holographic optical element assembly, the holographic optical element assembly including a holographic optical element (HOE), the assembly causing selected portions of the beam to interfere at a focal region after diffraction by the holographic optical element so as to reconstruct a real image of an aperture previously used to construct the HOE; ii) locating a record medium at the focal region so that the real image is recorded; and, iii) causing relative movement between the record medium and the interfering beam portions and repeating steps i) and ii) so that the real image is recorded at a plurality of locations or pixels on the record medium.

    摘要： A moiré magnification device including a transparent substrate carrying: an array of micro-focusing elements, the focusing elements defining a focal plane; a first array of microimage elements in a first colour and a second array of microimage elements in a second colour, the first and second arrays of microimage elements are located in a plane substantially coincident with the focal plane of the focusing elements, the second array of microimage elements being laterally offset from the first. The pitches of the micro-focusing elements, first and second arrays of microimage elements and their relative locations are such that the array of micro-focusing elements cooperates with each of the first and second arrays of microimage elements to generate respective magnified versions of the microimage elements due to the moiré effect. An interruption zone is perceived between the magnified versions of the first and second microimage arrays, respectively, and exhibits no magnified versions.
