摘要： An optical device includes a lightguide having a first pair of external surfaces parallel to each other, and at least two sets of facets. Each of the sets including a plurality of partially reflecting facets parallel to each other, and between the first pair of external surfaces. In each of the sets of facets, the respective facets are at an oblique angle relative to the first pair of external surfaces, and at a non-parallel angle relative to another of the sets of facets. The optical device is particularly suited for optical aperture expansion.

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 viewers (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 viewers, 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 viewers. 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： Embodiments of the disclosure provide a metrology system. In one example, a metrology system includes a laser source adapted to transmit a light beam, a lens adapted to receive at least a portion of the light beam from the laser source, a first beam splitter positioned to receive at least the portion of the light beam passing through the lens, a first beam displacing device adapted to cause a portion of the light beam received from the beam splitter to be split into two or more sub-light beams a first recording device having a detection surface, and a first polarizer that is positioned between the first displacing device and the first recording device, wherein the first polarizer is configured to cause the two or more sub-light beams provided from the first displacing device to form an interference pattern on the detection surface of the first recording device.

摘要： The pupil formed by an optical apparatus is expanded by use of a beam splitter to replicate the pupil and a waveguide to further replicate the replicated pupil. An optional rotator element can rotate a portion of the light split by the beam splitter to provide consistent polarization of light in the optical apparatus. In some embodiments, the beam splitter replication expands the pupil in one direction, while the waveguide replication expands the pupil in a second direction.
