Disclosed is a hologram stage setting which is configured to apply a net screen of a grid network structure coated by a ceramic ball lens on the front part of a stage and directly project images, thereby enabling performance without specific limits on general multi-purpose stages instead of special stages, solving high cost problems caused by using a conventional foil screen, implementing high-resolution images, enhancing durability, and performing easy maintenance and repair. The hologram stage setting includes: a rear screen which is installed on the rear part of a stage to display a rear background image; a lower screen which is installed on the lower part of the stage to display a lower background image; a front screen which is installed on the front part of the stage to display a front hologram image; and a front hologram image projector which generates and projects the front hologram image.

Embodiments described herein relate to lens-free imaging. One example embodiment may include a lens-free imaging device for imaging a moving sample. The lens-free imaging device may include a radiation source configured to emit a set of at least two different wavelengths towards the moving sample. The lens-free imaging device is configured to image samples for which a spectral response does not substantially vary for a set of at least two different wavelengths. The lens-free imaging device may also include a line scanner configured to obtain a line scan per wavelength emitted by the radiation source and reflected by, scattered by, or transmitted through the moving sample. The line scanner is configured to regularly obtain a line scan per wavelength. Either the radiation source or the line scanner is configured to isolate data of the at least two different wavelengths.

A machine is configured to perform hologram location within a scene to be generated. The machine accesses target motion data that describes movement of a target device. Based on the target motion data, the machine determines a target motion vector that indicates a target speed of the target device and indicates a target direction in which the target device is moving. The machine determines a hologram motion vector for a hologram to be generated for display by a user device. The hologram motion vector indicates a relative speed of the hologram and indicates a relative direction of movement for the hologram. The machine then causes the user device to generate a scene in which the hologram moves at a speed determined based on the target speed and on the relative speed, as well as moves in a direction determined based on the target direction and on the relative direction.

A system for motility contrast imaging a biological target within tissue comprising a CCD array; an illumination source for generating an incoming beam; a first beam splitter for receiving the incoming beam and producing an object beam and a reference beam; a second beam splitter for illuminating a multitude of biological targets with the object beam and for directing backscattered object beams towards the CCD array; a computer-controlled delay stage for zero-path-matching the reference beam to the backscattered object beams; a reference beam that intersects the backscattered object beams at an angle to produce a series of interference fringes that modulate Fourier-domain information; and a computer for receiving a time series of Fourier-domain information. The interference fringes between the backscattered object beam and the reference beam are recorded by the CCD array and passed to the computer which constructs a digital hologram at successive times.

A holographic elevator assistance system mounted in an elevator cab. The system includes a holographic display and a Common Passenger Interface Board (CPIB). The CPIB is configured to receive an input, interpret the received input, and perform a projection of a holographic image from the holographic display based on the input.

The present invention relates to an improved method for determining the identity of a biomolecule using interferometric light scattering apparatus, notably distinguishing between variants of biomolecules, such as viral serotypes and the like. Such a method has potential to simplify the testing for biological manufacture and for diagnosing disease, monitoring environmental issues and determination of contaminants.

Holographic projection of a digital object. A method includes identifying movement of a digital object in video content. The movement is along a path across a plurality of video frames of the video content. The method presents the video content on at least one display device. The presenting includes projecting a three-dimensional holographic image of the digital object adjacent to a surface of the display. The projecting traces the holographic image along the path across the plurality of video frames.

Systems, methods, and computer-readable media are disclosed for representing a transfer of a digital object using holographic images. User input is received that is indicative of a selection of the digital object for transfer from a sending device to a receiving device. Spatial attribute data is generated based at least in part on at least one of a distance or a relative orientation between the sending device and the receiving device, and a transition path is determined based at least in part on the spatial attribute data. Holographic image data is then generated based at least in part on the transition path, and the holographic image data is sent to one or more holographic projectors to cause a first holographic image representative of the digital object and a second holographic image representative of the transition path to be projected.

The invention is a method allowing particles to be tracked in a moving fluid, via an optical method. The particles are in motion in a fluidic chamber. An image of the fluidic chamber is acquired, so as to obtain three-dimensional positions of particles in the fluidic chamber at a first time. Three-dimensional positions of particles at a second time are also obtained, the second time being subsequent to the first time. On the basis of the obtained three-dimensional positions, potential movements of particles, between said times, are established. On the basis of a model of movement of the particles, potential movements are validated. The validated movements allow the particles in the fluid to be counted. In addition, if the particles are of different nature, the movement model may comprise a component of movement of the particles with respect to the fluid that is characteristic of this difference. Determining this component then allows the particles to be characterized.
