摘要： An attachment for an intensity-only sensor in an imaging device includes a polarization-sensitive diffraction grating. The polarization-sensitive diffraction grating is configured to receive incident light from a scene, and to modify the incident light to simultaneously produce a plurality of non-overlapping images of the scene, each of a different diffraction order, on the intensity-only sensor to facilitate full-Stokes imaging polarimetry. The attachment includes a first adjustment mechanism configured to control at least one of: vignetting of the plurality of non-overlapping images on the intensity-only sensor, or an object distance of the imaging device.

摘要： Systems, devices, and techniques for performing wavelength division multiplexing or demultiplexing using one or more metamaterials in an optical communications systems are described. An optical device may be configured to shift one or more phase profiles of an optical signal using one or more stages of metamaterials to multiplex or demultiplex wavelengths of optical signals. The optical device may be an example of a stacked design with two or more stages of metamaterials stacked on top of one another. The optical device may be an example of a folded design that reflects optical signals between different stages of metamaterials.

摘要： A multi-layered lens comprises a plurality of metasurface layers. At least some layers of the plurality of metasurface layers include features that exhibit angular phase controls. The angular phases of the at least some layers cause an angular aberration correction or an angle convergence that focuses light onto a focal point regardless of angles of incidence.

摘要： A collection of optical sub-elements can be arranged sequentially, such that they share a common optical axis through which light propagates. Each of these optical sub-elements can alter a phase, an amplitude, or a polarization of incident light, by virtue of its surface curvature, such as, for example, in a refractive optical element, or using microscale and nanoscale structures, such as, for example, in a diffractive optical element. One or more of these optical sub-elements can be rotated to tune one or more parameters, such as focal power, of the complete device.

摘要： A polarimeter includes an integrated device with an array of antennas including multiple column pairs. Each column pair has two columns, and each column in each column pair includes multiple antennas. A first column of each column pair in the array scatters a first polarization component of an incident radiation, and a second column of each column pair in the array scatters a second polarization component of the incident radiation. The scattered fields of the column pairs interfere constructively in a direction depending on the polarization of the incident radiation, resulting in maximal intensity at a certain point in space for a specific polarization state. Multiple column pairs in parallel and oriented at angles with respect to each other can be used to scatter different polarization components of the incident radiation directionally to different points in space. Detectors are positioned with respect to the integrated device to detect polarization components.
