Abstract: A light control material comprising a layer of photopolymer (131) having light traps (140) formed therein at selected locations. The photopolymer (131) layer constitutes a master from which embossments can be produced. The ligh traps (140) are formed in the master by reactively ion etching a layer of cured photopolymer (131) at selected locations to create fields of tapered structures (140). An embossment generated from the master contains fields of tapered structures (140) which correspond to those created in the master. The light control material is capable of operating in the reflective or transmissive modes. In the transmissive mode, the light traps (140) are coated with a reflective material, such as a reflective layer of metal. Light impinging on the light control material passes through the light control material except where the light enters the light trap (140). Light which enters the light trap (140) is absorbed. In the reflective mode, the entire surface of the light control material having the light traps (140) formed therein is coated with a reflective material such as metal. Light which enters the light traps (140) is reflected among the tapered structures (140) until substantially all of the light has been absorbed. Light which does not enter the light traps (140) is reflected. The method of the present invention can be used to produce color and black-and-white images as well as copy-resistant documents.

Abstract: A light control material generally comprising a transparent substrate (113) for carrying a print or photographic image and a plurality of focusing elements (114) which provide a field of view over which the brightness of the print or photographic image is enhanced. The field of view is controlled by the geometry of the focusing elements (142) including radius, width, and degree of symmetry. By providing a field of view (112) over which the brightness of the image is enhanced, the image may be viewed at angles which avoid the angles of specular reflection, which are usually seen as unwanted glare. Furthermore, selected portions of an image may be brightness enhanced more than others or selected portions may be brightness enhanced while others are not.

Abstract: A light control material having a two-layer optical system (Fig. 4a, its 31 and 32) producing autostereoscopic and dynamic images in thin-film materials. The first layer (31) comprises focusing optics which have a plurality of focusing elements. These elements may consist of refractive optics, binary optics, or mixed optics. The second layer (32) comprises light control optics having dark zones (34) and bright zones (33) for providing directional control of light through the focusing optics (31). The bright zones (33) may be comprised of a light transmissive material, or the light control optics may include a reflective layer for reflecting light at the bright zones. The dark zones (34) may be formed by creating light traps in the light control optics which absorb light. The light traps (Fig. 4b, it. 34) are comprised of structures having high aspect ratios. The light entering the light trap is reflected internally until all of the incident light has been absorbed. By controlling the number of bright zones (33) and dark zones (34) per focusing element (35), the field of view (Fig. 4c, it. 47) of an autostereoscopic or dynamic image can be controlled. A method for creating the light control material includes the steps of applying liquid photopolymer to opposite sides of a transparent substrate (Fig. 12) and embossing each side of the then created substrate to form the focusing and light control optics.
