摘要： An apparatus and method to produce a hologram of an object includes an electromagnetic radiation assembly configured to receive a received electromagnetic radiation, such as light, from the object. The electromagnetic radiation assembly is further configured to diffract the received electromagnetic radiation and transmit a diffracted electromagnetic radiation. An image capture assembly is configured to capture an image of the diffracted electromagnetic radiation and produce the hologram of the object from the captured image.

摘要： A method for displaying via a head-mounted display device a third party holographic portal in a user real world environment is disclosed. The method may include receiving a permission specifying a condition under which a third party is authorized to display the holographic portal in the user real world environment. A request may be received from the third party to display the third party holographic portal in the user real world environment. If the condition is satisfied and in response to the request, the head-mounted display device may display the holographic portal in the user real world environment, with the holographic portal comprising a visual representation of activity in a third party real world environment that is associated with the third party.

摘要： Provided is an illumination device for a projection device, which is appropriate to stereoscopic display and allows speckles to be inconspicuous. The illumination device includes: an optical element (50) which including a hologram recording medium (55) including a first zone Z1 and a second zone Z2 and can reproduce an image 5 of a scattering plate 6; an irradiation device (60) which irradiates the optical element with a coherent light beam such that the light beam is allowed to scan the hologram recording medium; and a polarization control unit (70) provided on an optical path of the light beam to an illuminated zone (LZ). The light beams incident on respective positions of the hologram recording medium are allowed to reproduce the image superimposed on the illuminated zone. The polarization control unit (70) controls polarization of the light beams such that the light beam incident on the first zone to travel toward the illuminated zone and the light beam incident on the second zone to travel toward the illuminated zone are configured with different polarization components.

摘要： A computer-implemented method for analyzing digital holographic microscopy (DHM) data for hematology applications includes receiving a DHM image acquired using a digital holographic microscopy system. The DHM image comprises depictions of one or more cell objects and background. A reference image is generated based on the DHM image. This reference image may then be used to reconstruct a fringe pattern in the DHM image into an optical depth map.

摘要： A method for lens-free imaging of a sample or objects within the sample uses multi-height iterative phase retrieval and rotational field transformations to perform wide FOV imaging of pathology samples with clinically comparable image quality to a benchtop lens-based microscope. The solution of the transport-of-intensity (TIE) equation is used as an initial guess in the phase recovery process to speed the image recovery process. The holographically reconstructed image can be digitally focused at any depth within the object FOV (after image capture) without the need for any focus adjustment, and is also digitally corrected for artifacts arising from uncontrolled tilting and height variations between the sample and sensor planes. In an alternative embodiment, a synthetic aperture approach is used with multi-angle iterative phase retrieval to perform wide FOV imaging of pathology samples and increase the effective numerical aperture of the image.
