摘要： A system includes a surface relief grating configured to forwardly diffract an input beam as two linearly polarized beams. The system also includes a waveplate optically coupled with the surface relief grating and configured to convert the two linearly polarized beams into two circularly polarized beams having orthogonal circular polarizations. The two circularly polarized beams having orthogonal circular polarizations interfere with one another to generate a polarization interference pattern.

摘要： A holographic display device comprises an OLED array writing onto an OASLM, the OLED array and OASLM forming adjacent layers. The OASLM encodes a hologram and a holographic reconstruction is then generated by the device when an array of read beams illuminates the OASLM. The OASLM is suitably controlled by the OLED array. An advantage of the device is that it lends itself to compactness.

摘要： An image reproducing apparatus having a small size and which is highly portable reproduces an image contained within a hologram or holographic stereogram. In one embodiment, when a movable section movably attached to an apparatus body is moved from a first position, in which the movable section abuts the apparatus body, to a second position in which the movable section and apparatus body are separated, illumination light from a light source is irradiated at a predetermined incidence angle onto a hologram or holographic stereogram attached to a hologram attach section. In other embodiments, light from a light source is reflected from an edge portion of a light transmitting member, or from a separately provided mirror, to be irradiated at a predetermined angle onto the hologram or holographic stereogram.

摘要： A head-mounted display device for generating reconstructions of three-dimensional representations including a frame, in which at least one light source, at least one optical system and at least one encodable light modulator are situated, wherein the light modulator with an encoding of a wavefront of the three-dimensional representation in the encoding area is positioned at the place of an observer window defined in an observer plane or the light modulator with an encoding of a hologram of the wavefront of the three-dimensional representation in the encoding area is positioned in the region closely in front of the observer window for transforming the hologram into the observer window. When the light modulators are illuminated, complex wavefronts of the three-dimensional representation are situated in the observer window and the reconstruction of the three-dimensional representation is visible in a visual cone spanned by the observer window and the light modulator.
