Abstract:
A method for transferring a holographic design on a multilayer polyethylene film having DSC (Differential Scanning Calorimeter) melting point less than or equal to 119 degrees centigrade is provided. The holographic film has higher interlayer bond strength against PET (polyethyleneterephthalate) or BOPP (Biaxially oriented polypropylene) enabling surface printing on the other side layer of the multilayer of the holographic film. The films have good oxygen and moisture barrier properties and therefore can be used be used for manufacturing attractive holographic tubes for food product, toothpaste, cosmetics etc.
Abstract:
The present invention relates to a light modulating device, comprising a SLM and a pixelated optical element, in which a group of at least two adjacent pixels of the SLM in combination with a corresponding group of pixels in the pixelated optical element form a macropixel, the pixelated optical element being of a type such that its pixels comprise a fixed content, each macropixel being used to represent a numerical value which is manifested physically by the states of the pixels of the SLM and the content of the pixels of the pixelated optical element which form the macropixel.
Abstract:
Disclosed is a holographic display including a spatial light modulator, and including a position detection and tracking system, such that a viewer's eye positions are tracked, with variable beam deflection to the viewer's eye positions being performed using a microprism array which enables controllable deflection of optical beams.
Abstract:
The present disclosure features processes and equipment for forming a variety of textured materials, including both release webs, and finished products such as flooring materials, wall coverings, textured laminates and the like. The processes described herein allow curing radiation to be passed through a texturing medium, rather than through the substrate to which the curable material is applied.
Abstract:
We propose a method of detecting the presence of certain chemical and biochemical substances by virtue of the fact that they are, or have attached to them, either a dye molecule which acts as a photosensitizer for a holographic recording or erasing process, or another essential molecular component of the holographic recording material such as a monomer or a free radical generator. A recording material used in the process utilizes a photopolymer system consisting of a monomer and a crosslinking monomer, a free radical generator, a photosensitizer and, additionally, a polymeric binder when dry formulations are required and specifically lacks the substance to be detected. Subsequent holographic exposure records an interference pattern only where the complementary substance is present. Applications are broad ranging. Examples in diagnostics, printing, security, and environmental monitoring are given.

Abstract:
A holographic display device comprising at least one magneto-optical spatial light modulator (MOSLM). The holographic display device may comprise a first MOSLM (53, 54) and a second MOSLM (56, 57), the first and second MOSLMs encoding a hologram and a holographic reconstruction being generated by the device. An advantage of the device is fast encoding of holograms.
Abstract:
Holographic display (136) device comprising a first EASLM (132) and a second EASLM (132), the pair permitting independent modification of phase and amplitude, in which holographic reconstruction is visible through one or more virtual observer windows. An advantage is that an observer may view a holographic reconstruction through one or more virtual observer windows from a device housing a pair of EASLMs which permit independent modification of phase and amplitude.
