    Abstract: A display panel assembly comprises a transflective holographic screen, i.e., a transparent screen that reflects light from a projection system, comprising at least a volume hologram, a first protective element and a second protective element, each arranged in contact with the volume hologram such that the volume hologram is sandwiched between the first protective element and the second protective element. The display panel assembly further comprises a projection system focusing an image on the volume hologram comprising at least projection optics, mounting means arranged to fixedly mount the projection system relatively to the transflective holographic screen. The volume hologram comprises a plurality of diffractive patterns disposed in sequence across the volume hologram, each of the plurality of diffractive patterns being configured to diffuse the light rays from the projection system in a determined direction corresponding to the specific diffractive pattern and oriented towards a position of an intended eye of a user wearing the display panel assembly.

    Abstract: Laser ablation to direct write dot matrix holographic patterns onto the surface of polymeric coatings deposited on an embossing cylinder is described. The desired holographic pattern is ablated by interfering at least two laser beams directly onto the polymeric coating of the embossing cylinder in the pixel-by-pixel manner. The direct write laser ablation technique eliminates the size limitations of the holographic pattern created on the surface of the embossing cylinder, the need to combine smaller images to create a larger shim and the very need to use the shims, since large seamless embossing cylinders can be directly pixel-by-pixel ablated with larger sized images of great variety. The polymeric coatings for further direct write laser ablation can be deposited onto the embossing cylinder by various methods, including, but not limited to, molding or coating.

    Abstract: A surface microstructure is superimposed on the surface of a replication mould such as an injection moulding tool insert by laser interference exposure of a mask pattern and etching or electroplating the additional microstructure. The technique enables the post-processing of planar and non-planar replication moulds with additional microstructure to improve the functionality and value of the moulded components. A major area of application is an anti-reflection surface for injection moulded polymer optical components, achieved by the superposition of submicrometer anti-reflection grating structure onto injection moulding tool inserts.

    Abstract: The invention relates to a method for producing a diffraction grating (20) for a diffractive optical element having one or more subareas (22) which comprises respective grating patterns defined by a grating constant and an angular orientation. The inventive method is characterized by setting the position of at least one source (12) from which radiation is incident on the diffraction grating (20) and the position of at least one target (18) towards which the diffraction grating (20) is intended to deflect the radiation. The spatial position and orientation of the subareas (22) and the grating constant and the angular orientation of the grating patterns required to deflect the radiation incident from the source (12) on the diffraction grating (20) towards the target (18) is determined using a local vector relation which correlates the orientation of the grating in a three-dimensional space with the incident and emergent radiation and the position and orientation of the grating patterns.
