摘要： An optionally transferable optical system with a reduced thickness is provided. The inventive optical system is basically made up of a synthetic image presentation system in which one or more arrangements of structured image icons are substantially in contact with, but not completely embedded within, one or more arrangements of focusing elements. The focusing element and image icon arrangements cooperate to form at least one synthetic image. By way of the subject invention, the requirement for an optical spacer to provide the necessary focal distance between the focusing elements and their associated image icons(s) is removed. As a result, overall system thicknesses are reduced, suitability as a surface, applied authentication system is enabled, and tamper resistance is improved.

摘要： A manufacturing system includes a sensing system that provides high-resolution feedback for web guiding and tension control. The system may be especially useful for web material that is manufactured to include micro-replicated structures with micron size scale. A micro-replication station forms a pattern of micro-replicated lenses on a web material. The sensing system illuminates a measurement area on the web material and detects an angular distribution of light exiting a set of the micro-replicated lenses within the first measurement area. A control system that adjusts at least one process control parameter of the transport system based on the detected angular distribution.

摘要： A replication tool for producing an optical structure comprising an optical element includes a central section having the shape defining a negative of a portion of the optical structure and a vertically aligned central axis; a surrounding section laterally surrounding the central section; and one or more contact standoffs defining a plane referred to as contact plane. In a first azimuthal range, the surrounding portion provides a first compensation surface facing away from the central axis, and in a second azimuthal range, the surrounding portion provides a second compensation surface facing away from the central axis. In any cross-section containing the central axis in the second azimuthal range, a steepness of the second compensation surface is higher than a steepness of the first compensation surface in any cross-section containing the central axis in the first azimuthal range.
