Abstract: Mastering systems and methods of fabricating waveguides and waveguide devices using such mastering systems are described. Mastering systems for fabricating holographic waveguides can include using a master to control the application of energy (e.g. a laser, light, or magnetic beam) onto a liquid crystal substrate to fabricate a holographic waveguide into the liquid crystal substrate. Mastering systems for fabricating holographic waveguides in accordance with embodiments of the invention can include a variety of features. These features include, but are not limited to: chirp for single input beam copy (near i.e. hybrid contact copy), dual chirped gratings (for input and output), zero order grating for transmittance control, alignment reference gratings, 3:1 construction, position adjustment tooling to enable rapid alignment, optimization of lens and window thickness for multiple RKVs simultaneously, and avoidance of other orders and crossover of the diffraction beam.

Abstract: A system and method may utilize holography to facilitate fabrication techniques such as 3D printing and lithography. The system may include a light source, a hologram of an original object or lithographic pattern recorded in a holographic medium, and a target such as a reservoir of photosensitive material or a photosensitive material attached to a substrate. Illuminating the hologram with the appropriate light source may cause a holographic image of the original object or lithographic pattern to form on the photosensitive material within the reservoir or on the substrate. Formation of the holographic image may result in the formation of a new object from the photosensitive material, or may facilitate removal or retention of photosensitive material as part of a lithographic process.

Abstract: A method and a device produce an individualized hologram from a generated light beam. According to the method, the light beam is individually modulated in a spatial light modulator, a holographic recording material is arranged relative to a holographic master, and the individually modulated light beam is guided in such a manner that at least part of the individually modulated light beam is refracted and/or reflected on the holographic master and an interference pattern representing the individualized hologram is produced in the holographic recording material. The individually modulated light beam is displaced relative to the holographic recording material and the holographic master to scan the entire holographic master. The recording material is arranged so as to rest on a cylindrical drum or a cylindrical drum segment and the drum is rotated about a drum axis of the drum or the drum segment during scanning of the holographic master.

Abstract: We describe techniques for recording a holographic image onto holographic recording film, in particular for security holograms. We thus describe a structure having a stack comprising the holographic recording film and a multichannel image generation device under the film. A three-dimensional object (or hologram of a 3D object) is provided, located under the multichannel image generation device. At least a portion of the multichannel image generation device is substantially transparent or absent in a region above the object. A holographic image is recorded in the film by illuminating the stack with laser light. The multichannel image generation device under the film may comprise a volume reflection hologram of a lenticularly generated image. The structure records a hologram of the 3D object in conjunction with a multi-channel holographic image.

Abstract: Three-dimensional holographic elements are disclosed. Three-dimensional Bragg gratings recorded on bulks of optical material are included in the disclosure. Such elements may be manufactured by placing a three-dimensional bulk of optical material directly behind a recorded master hologram, directing a reference beam onto a master hologram such that a replica of the master hologram is recorded in the optical material. The replica may form the three-dimensional holographic element. The master hologram may be Bragg grating formed on a surface of a transparent substrate.

Abstract: The present invention concerns methods and devices for creating and printing variable size and variable resolution holographic stereograms and holographic optical elements using computer rendered images of three-dimensional computer models or using computer processed images. The present invention is an apparatus and method for printing one-step, full-color, full-parallax holographic stereograms utilizing a reference beam-steering system that allows a reference beam to expose a holographic recording material from different angles. More particularly, a coherent beam is split into object and reference beams. The object beam passes through an object beam unit in which a rendered image is displayed, while the reference beam passes through the reference beam-steering system. The object and reference beams interfere with each other at an elemental hologram on a holographic recording material. A computer controls the exposure time and the movement of the recording material and may also render the images displayed in the object beam unit. In addition, the computer may also store the images before they are displayed in the object beam unit. Also, the present invention may also utilize a voxel-control lens placed in the path of the object beam and in close proximity to the holographic recording material to control the resolution of a holographic stereogram. In addition, the present invention may also utilize interchangable band-limited diffusers and reference-beam masking plates. Furthermore, the present invention incorporates viewing zone techniques to the rendering process for one-step, holographic stereograms to produce animated, one-step, holographic stereograms.

Abstract: An information-recorded medium that contains a holographically-recorded bar code and a method for using this medium to achieve enhanced security and authentication of bar code readings in commerce are described. The holographically-recorded bar code is virtually impossible to copy by non-holographic means and is readable using conventional bar code scanners that are currently in use. The holographically-recorded bar code can be made either visible or invisible to the human eye and can be made responsive to electromagnetic radiation in the visible, ultraviolet, and infrared regions of the spectrum.
