    Abstract: A method of recording a master hologram comprises projecting a beam of coherent light, e.g. using a laser (1) through, in turn, a holographic recording medium (8) and a transparent object (22), into a diffuse reflective surface (23), wherein the object is non-holographic and wherein the medium, the object and the surface are in substantially linear arrangement such that light reflected by the surface interferes in the medium with light projected therethrough.

    Abstract: The invention relates to a sensor comprising a medium and, disposed therein, a hologram, wherein an optical characteristic of the medium changes as a result of a variation in a physical property of the medium, wherein the fringes of the hologram are formed by silver grains and wherein the medium comprises a material which does not bind silver. The brightness and sensitivity of such holographic sensors is increased as a result of reduction in the levels of unwanted (“background”) silver binding.

    Abstract: A method of making a product containing a hologram which has at least two replay colours when viewed at a given angle, the method comprising the steps of: (i) recording holographic elements at each of at least two different angles in a master; and (ii) copying the master. The principle of the system is demonstrated by creating 2 surface relief objects, A and B on top of a mirror background. When a holographic recording medium is placed on top of this surface relief object and then illuminated with a coherent laser beam, interference patterns are recorded and developed within the polymer which describe the relief patterns (C-E). When the hologram is illuminated with white light and viewed normal to the hologram surface, the separation between the fringes relative to the viewing angle then becomes da and dc for surface relief objects A and B respectively (Figures C and E) and remains the same for the mirror (Figure D). This will then result in different frequencies of light or different colours being reflected at each specific viewing angle.
