摘要： A head-mounted display device comprises a rendering engine configured to generate a hologram representative of a three-dimensional object. The hologram includes depth information that causes the three-dimensional object to be rendered with a focus that is determined by the depth information. The device also includes a spatial light modulator that modulates light from a light source as indicated by the hologram. A switchable hologram comprises multiple stacked switchable gratings. Each of the stacked switchable gratings is associated with one or more resulting exit pupil locations on a viewing surface. The system also comprises an eye tracker configured to map a viewing direction of a user's eye to a viewing location on the viewing surface. A processor is configured to activate a particular switchable grating within the switchable transmission hologram that is associated with an exit pupil location that aligns with the viewing location.

摘要： A compact, self-contained holographic and interferometric apparatus and methods for eliminating vibration, including methods for eliminating relative displacement and vibration errors present in object and reference beam paths, are disclosed. The self-contained apparatus (600) includes an illuminated object (302) that scatters light and an objective lens (304) to form an object beam (350). The self-contained apparatus also includes a reference beam forming lens group (308) that forms a reference beam (352) from a portion of the object beam that passes through a pupil plane (306) of the objective lens (304). The object beam and the reference beam are propagated along a shared optical path, which eliminates relative displacement and vibration errors. The self-contained apparatus includes an image plane (316) where the object beam and reference beam are recombined to create an interference pattern, which is detected and analyzed. Methods for eliminating the instability, using the self-contained apparatus, are disclosed.

摘要： An apparatus for detecting a 3D structure of an object. The apparatus has first and second laser emitters which generate laser radiation having first and second wavelengths, respectively, the first wavelength being different from the second wavelength. Optical devices are disclosed, including a beam splitter, which splits the laser radiation of the laser emitters in each case into a reference radiation and an illuminating radiation. The illuminating radiation impinges upon the object to be measured, is reflected by the object as object radiation and interferes with the reference radiation. A detector receives the interference patterns. The laser emitters are located such that the illuminating radiation of the first and second laser emitters impinge upon the object at different angles of incidence. Also discussed is a measuring device which measures the two wavelengths of the laser radiation of the laser emitters and influences the recording of the interference patterns.

摘要： A method for the production of a holographic sensor which comprises a support medium supporting a reflection hologram wherein the support medium interacts with its physical or chemical environment to create an optical response which is a change in one or more optical properties of the hologram, the method comprising the steps of: a) introducing a colloidal dispersion of a recording material into the support medium; and b) ablating the colloidal particles of the recording material using a pulsed laser to form the holographic element in the support medium. The method of production can be used to introduce a reflection holographic grating into a hydrophobic support medium, in particular, polydimethylsiloxane (PDMS), which possesses an extraordinary ability to swell in the presence of both liquid and/or gaseous low molecular weight hydrocarbons and organic solvents and thus has many applications as a holographic sensor.

摘要： This invention relates to methods, apparatus, and computer program code for the holographic display of images. We describe a method of displaying an image holographically. The method includes displaying a hologram on pixels of a spatial light modulator (SLM) and illuminating the SLM such that the image is displayed in pixels of a replay field (RPF) of the hologram. The method further includes subdividing the replay field into a plurality of spatially interlaced regions, and displaying holograms for each of the interlaced regions of the replay field sequentially at different times such that in an observer's eye the interlaced regions integrate to give the impression of the image and such that interference between adjacent pixels of the replay field is reduced.
