Holographic image display system

Disclosed are methods and systems for displaying images, and for implementing volumetric user interfaces. One exemplary embodiment provides a system comprising: a light source; an image producing unit, which produces an image upon interaction with light approaching the image producing unit from the light source; an eyepiece; and a mirror, directing light from the image to a surface of the eyepiece, wherein the surface has a shape of a solid of revolution formed by revolving a planar curve at least 180° around an axis of revolution..

Method of laser illumination with reduced speckling

Proposed is a method of laser illumination with reduced speckling for in optical microscopy, machine vision systems with laser illumination, fine optical metrology, etc. The method comprises forming a net of planar ridge waveguides into an arbitrary configuration and providing them with a plurality of holograms having holographic elements formed into a predetermined organization defined by the shape of a given light spot or light field which is to be formed by light beams emitted from the holograms on the surface of the object or in a space at a distance from the planar ridge waveguide.

Security element comprising a volume hologram

The present invention relates to a security element (20) to be built into an item, particularly a document (10), said security element comprising a holographic layer, enabling a volume hologram to be generated, and a non-holographic variable opacity structure generated by the presence of: a) one or more cutout(s) and/or at least partially translucent areas and moreover at least partially opaque area(s); and/or b) oriented platelet pigments. The variable opacity structure is at least partially placed over the hologram within a region of the security element observable in transmitted light..

Top coupled photonic chip alignment package

The present invention provides an improved coupling and improved alignment of top-coupled photonic chips. The present invention includes a method to package and align top-coupling photonic chips using a holographic grating coupler and v-groove placement comprising the steps of: preparing the photonic chip with grating couplers, preparing the fibers by polishing the ends, preparing the cap chip by defining v-grooves to complement the photonic chip, attaching the fibers to the v-block cap chip, and top-cladding the cap chip to the photonic chip.
