| 20110310485 | OPTICAL DEVICE AND METHOD OF MANUFACTURE - The present invention provides for a diffractive structure comprising a plurality of grooves each formed by a plurality of two-dimensional scattering and/or diffractive groove elements, aligned in a manner serving to provide for at least one diffractive optical effect and further a surface display device comprising a plurality of regions wherein each region has a diffractive surface relief structure as defined above and wherein the gratings of one of said regions at an angle relative to the gratings of another of said regions. | 12-22-2011 |
| 20090153967 | OPTICAL SECURITY DEVICE OFFERING 2D IMAGE - The present invention provides for a diffractive element comprising a diffractive optical microstructure consisting of a modulated structure of a diffractive type which upon illumination by diffused ambient light creates a two-dimensional image to be viewed by an observer upon tilting or rotating the device or by varying lighting direction, wherein the diffractive modulated structure of the device consists of various generally parameterised special optical elements with specifically prescribed groove shapes, wherein each groove shape, position, centre(s), and line thickness, are described by functions describing those dependencies which are variables of the positional coordinate of the optical element. | 06-18-2009 |
| 20090091834 | METHOD OF CREATING A THREE-DIMENSIONAL IMAGE, A DIFFRACTIVE ELEMENT AND METHOD OF CREATING THE SAME - The invention discloses a diffractive device and a method of creating the same displaying a three-dimensional preferably achromatic image, especially imitating a real or an imaginary relief scene, a flat microrelief or otherwise modulated structure ( | 04-09-2009 |
