    摘要: A visual display assembly useful as an authentication or anti-counterfeiting element. The assembly includes a substrate and, on a surface of the substrate, an array of micro mirrors receiving ambient light. Each mirror includes a reflective surface reflecting the ambient light to display an image that appears to float in a plane, which is spaced a distance apart from the surface of the substrate. The image includes a plurality of pixels, and the array of micro mirrors includes for each of the pixels a set of the micro mirrors each having a reflective surface oriented to reflect the ambient light toward a point on the plane corresponding to one of the pixels. Each of the sets of the micro mirrors includes a plurality of the micro mirrors, and the reflected ambient light each set of micro mirrors intersects to illuminate or write a pixel of an image.

    摘要: A synthetic-image device (1) comprises an image layer and a focusing element array. Composite image objects of the image layer are a merging of at least a first and a second set of image objects. The first set of image objects are arranged for giving rise to a guiding synthetic image (41). The guiding synthetic image, when being moved to be viewed in a direction, presents a first part image and a second part image moving towards a predetermined relative geometrical relation with respect to each other. The second set of image objects is arranged for giving rise to an effect synthetic image (42) within a limited effect field of view. The limited effect field-of-view is selected as including viewing directions only in angular vicinity of any of the direction, or excluding viewing directions only in angular vicinity of any of the direction.

    摘要: An optical device is disclosed comprising an array of reflecting surface relief structures projecting from or recessed into a base plane of the device. The structures generate an optical effect including a floating image at least when the device is viewed by an observer from a first position relative to an axis perpendicular to the base plane of the device. The floating image changes to another type of floating image or to a non-floating image when the device is rotated about the axis. A method of manufacturing an optical device is also disclosed.
