Abstract: Systems and methods are described for providing a 3D display, such as a light-field display. In some embodiments, a display device includes a light-emitting layer that includes a plurality of separately-controllable pixels. A lens structure overlays the light-emitting layer. The lens structure includes an array of collimating optical elements. A phase-modifying layer is positioned between the light emitting layer and the lens structure. The pixels of the light emitting layer are used in generating spatial emission patterns that work in unison with the phase-modifying layer in order to generate beams of light through the collimating optical elements with extended focus depths. Multiple beams are used to generate voxels at various distances from the display surface with the correct eye convergence for the viewer. Beams with extended focus depths may be used to generate the correct eye retinal focus cues.

Abstract: A spectral imaging device comprises: an optical modifier system (SYS1) to form axial light beams (LB2) from received light beams (LB1), the axial light beams (LB2) being parallel with an optical axis (AX1) of the imaging device (500), a Fabry-Perot interferometer (FPI) to provide filtered axial light beams (LB3) by filtering light of the axial light beams (LB2), an image sensor (SEN1), and an array (ARR1) of lenses (LNS0,0, LNS0,1) to form a plurality of sub-images (S0,0, S0,1) on the image sensor (SEN1) by focusing light of the filtered light beams (LB3).

Abstract: Display methods and apparatus are described. In some embodiments, to generate an image, light is selectively emitted from one or more light-emitting elements (such as a ?LEDs) in a light-emitting layer. The emitted light from each element is collimated using, for example, an array of microlenses having small apertures. Each beam of collimated light is split by a first diffractive grating into a first generation of child beams, and the first generation of child beams is split by a second diffractive grating into a second generation of child beams. Beams in the second generation of child beams that are not parallel to the original beam of collimated light may be blocked by a spatial light modulator (e.g. an LCD panel). The un-blocked beams operate in some respects as if they had been generated using optics with an aperture larger than the apertures of the microlenses.
