摘要： The problem of 3D panel display systems either (a) requiring special glasses to separate left and right images, or (b) having auto-stereoscopic 3D with compromised fidelity, is solved by providing, for each of a plurality of left and right sub-pixels, both (1) means for separating the left and right image signals (e.g., alternating wedges, prisms, off-axis self-sourcing pixels, etc.), and (2) means for multiplexing the separated left and right signals to a plurality of users (e.g., gratings, such as amplitude gratings, phase gratings, etc.), such that (1) the left image is provided to a plurality of virtual volume apertures (VVAL) containing positions of the left eyes of the plurality of users, and (2) the right image is provided to a plurality of virtual volume apertures (VVAR) containing positions of the right eyes of the plurality of users. Glass-free 3D systems consistent with the present invention may treat far field optical signals from the display panel as electro-magnetic waves (and therefore treat diffraction and interference properties as significant, dominating far field optical distribution) rather than as rays consistent with geometric optical theory.

摘要： The problem of 3D panel display systems either (a) requiring special glasses to separate left and right viewing images, or (b) having auto-stereoscopic 3D with compromised fidelity, is solved by providing a projection three dimensional (3D) display system for providing glass-free, 3D display to a plurality of viewing volumetric pairs (VVAs) in space corresponding to a hypothetical plurality of viewers' eye aperture pairs, the projection 3D display system comprising: (a) a dual-image projector configured to project both a left viewing tri-color image and a right viewing tri-color image; and (b) means for (1) receiving a tri-color mixed input beam encompassing the left and right viewing tri-color images, (2) multiplying the tri-color mixed input beam into a plurality of tri-color mixed output beams, and (3) focusing the plurality of tri-color mixed beams for viewing at the VVAs.

摘要： A holographic 3D display system is described that (1) always presents true-colored and true-orthoscopic 3D images regardless of whether the object is thin or thick, or the image is virtual or real and (2) accomplishes an effective data/signal compression apparatus that accommodates to both off-the-shelf detector and display arrays, of both amicable gross array dimensions and palpable individual pixel sizes. It provides a rectilinear-transforming digital holography (RTDH) system for recording and displaying virtual, real, or both virtual and real, orthoscopic three-dimensional images, the system comprising: (a) a focal-plane compression-domain digital holographic recording/data capturing (FPCD-DHR) sub-system; (b) a 3D distribution network for receiving, storage, processing and transmitting the digital-holographic complex wavefront data signals generated by the digital complex wavefront decoder (DCWD) to at least one location; and (c) a focal-plane compression-domain digital holographic display (FPCD-DHD) sub-system located at the at least one location.

摘要： A fiber optic bioprobe in which an immobilized biolayer, such as an antigen or antibody, acts as a sensing etalon of a Fabry-Perot interferometer. The bioprobe is used in a system in which a shift in the spectral dispersion pattern, caused by reflected out-of-phase beams, is used to determine a concentration of a substance in a sample solution.
