摘要： We describe methods of mass-producing full colour, 3D holograms, potentially incorporating a personalised image, which are particularly suitable for security purposes. Broadly speaking in embodiments a method generates, electronically, an interlaced image comprising a set of different views of a 3D object from different angles. This is projected onto a diffusing screen using coherent light and mapped from the screen into an angularly encoded object beam using a lenticular array. The different views in the angularly encoded object beam are then recorded simultaneously into holographic film using a reference beam.

摘要： The present invention relates to a method and apparatus for producing a hologram, in particular a dot matrix volume hologram. A holographic recording system (1) comprises a source of optical radiation (7), a transparent or partially transparent holographic recording medium 6 and an optical system (10). The recording medium (6) has a first side (25), a second side (26) and a recording volume (36), the second side (26) being opposite to said first side (25) and the recording volume (36) being between said sides (25, 26). The recording medium (6) is positioned between the source of optical radiation (7) and the optical system (10) so that the first side (25) is presented towards the source of optical radiation (7) and the second side (26) is presented towards the optical system. The source (7) is arranged to project incident optical radiation (20) onto the first side (25) and through the recording volume (36) towards the optical system (10). The optical system (10) is arranged to redirect (32) the optical radiation back onto said second side (26) and into the recording volume (36) so that said incident (20) and redirected (32) optical radiation intersect within the recording volume (36) at an obtuse angle (34) to create an interference pattern (38) from which a holographic recording may be made.

摘要： A holographic recording system (1) includes a transparent or semi-transparent holographic recording medium (6), a source of coherent optical radiation (7), and an optical system (10). The recording medium has a first side (25) presented toward the radiation source, a second side (26) opposite to the first side and presented toward the optical system, and a recording volume (30) between the two sides. The radiation source is arranged to project incident optical radiation (20) onto the first side and through the recording volume towards the optical system, which is arranged to redirect (32) the optical radiation back onto the second side and into the recording volume so that the incident and redirected radiation intersect within the recording volume at an obtuse angle (34) to create an interference pattern (38) from which a holographic recording may be made.
