摘要： A compact and light-weight lens-free platform to conduct automated semen analysis is disclosed. The device employs holographic on-chip imaging and does not require any lenses, lasers or other bulky optical components to achieve phase and amplitude imaging of sperm a relatively large field-of-view with an effective numerical aperture of approximately 0.2. A series of digital image frames is obtained of the sample. Digital subtraction of the consecutive lens-free frames, followed by processing of the reconstructed phase images, enables automated quantification of the count, the speed and the dynamic trajectories of motile sperm, while summation of the same frames permits counting of immotile sperm.

摘要： In-line holography to create images of a specimen, such as one or more particles dispersed in a transparent medium. Analyzing these images with results from light scattering theory yields the particles' sizes with nanometer resolution, their refractive indexes to within one part in a thousand, and their three dimensional positions with nanometer resolution. This procedure can rapidly and directly characterize mechanical, optical and chemical properties of the specimen and its medium.

摘要： We describe a method of displaying an image holographically using a spatial light modulator (SLM), the SLM having a plurality of pixels, the method including: displaying a diffraction pattern on the pixels of the SLM; and illuminating the pixels such that light diffracted by said diffraction pattern on the SLM pixels includes a content of said displayed image. A variation in brightness of said displayed image across the displayed image is modulated by an intensity envelope determined by the diffraction pattern of an individual said pixel, for example a sinc envelope. The method further includes moving a peak or centre of gravity of the intensity envelope away from a zero order spot and towards a centre of the displayed image by imposing a pattern of phase delay across the SLM pixels, the pattern of phase delay repeating at a spatial interval corresponding to a pixel interval of the SLM.

摘要： The invention relates to a method for generating video holograms for a holographic reproduction device with at least one light modulation means, wherein a scene split into object points is encoded as a whole hologram and can be seen as a reconstruction from a visibility region, which is located within a periodicity interval of the reconstruction of the video hologram. The visibility region, together with each object point of the scene to be reconstructed, defines a subhologram and the whole hologram is generated from a superposition of subholograms, wherein in a sequence of image contents the difference subholograms of object points are preferably generated for each picture, differing in regards to the visibility according to the viewer position in sequential images of the sequence. The display device comprises means that provide high-quality video holograms in spite of the data amount being significantly reduced.

摘要： An optical switch uses two ferroelectric liquid crystal spatial light modulators (10, 11) with an interconnect region in between. The switch uses bulk lenses (2, 8) to focus light from an input fibre array (1) to a first spatial light modulator (10), and from the second spatial light modulator (11) to an output array (9). Each spatial light modulator displays a respective hologram selected from a previously calculated set, to cause a desired switching of light from the input fibre array to the output array.

The method includes performing the following steps for each calibration image in order to determine a plurality of displacements vectors at a respective plurality of different locations on the replay plane: projecting the calibration image onto the replay plane using a first colour holographic channel by displaying a first hologram on a first spatial light modulator and illuminating the first spatial light modulator with light of the first colour; projecting the calibration image onto the replay using a second colour holographic channel by displaying a second hologram on a second spatial light modulator and illuminating the second spatial light modulator with light of the second colour, the first and second hologram corresponding to the calibration image; determining the displacement vector between the light spot formed by the first colour holographic channel and the light spot formed by the second colour holographic channel; and pre-processing an image for projection using the second colour holographic channel in accordance with the plurality of determined displacement vectors.

摘要： A method for ascertaining a diffraction characteristic of a hologram element for smart glasses. The method includes a step of outputting a light beam to an observation position on the hologram element by means of a light source, the light beam having at least one predefined wavelength and at least one sending parameter associated with the wavelength. The method also comprises a step of acquiring at least one reflection beam reflected at the observation position and/or transmission beam of the light beam having the predefined wavelength and transmitted through the hologram element at the observation position using at least one detector, wherein a detection parameter of the reflection beam and/or of the transmission beam is acquired at the predefined wavelength, and a step of comparing the sending parameter with the detection parameter in order to ascertain the diffraction characteristic of the hologram element at the observation position.

摘要： An apparatus for, and method of, image reconstruction. The method includes first breaking a holographic image into a plurality of interlaced sample sets corresponding to color separation images; and independently sampling, filtering, and reconstructing all sets. The resulting demodulated images contain no fringes. Notably, range-clipped tonal rendering curves are used to choose pixel regions of the demodulated images that will replace saturated regions. The image is reconstructed by integrating all un-saturated images into one.
