摘要： An apparatus includes, in some implementations, at least one image sensor, a plurality of metalenses, and readout and processing circuitry. The at least one image sensor includes pixel arrays, each of which is associated, respectively, with a different one of multiple optical channels configured for detection of incoming light rays of a respective color. The color for each optical channel differs from that of at least one of the other optical channels. Each of the metalenses is disposed, respectively, in a different one of the optical channels and is configured, respectively, to focus incoming light rays onto a different one of the pixel arrays. The readout and processing circuitry is operable to read out signals from the pixel arrays and to generate a respective lower-resolution image for each of the optical channels, and to process the lower-resolution images to obtain a higher-resolution multi-color image. Methods of operation are described as well.

摘要： Metasurfaces and systems including metasurfaces for imaging and methods of imaging are described. In one embodiment, a method for acquiring images by an imaging system comprising a metalens includes: illuminating the metalens; acquiring light passing through the metalens as a first image by an image sensor; and processing the first image into a second image that is a deconvolved version of the first image by a post-processing engine.

摘要： A metalens includes one or more regions of nanostructures. A first region of nanostructures directs a first field of view (FOV) of light incident on the first region of nanostructures to a first region of an image plane. A second region of nanostructures directs a second FOV of light incident on the second region of nanostructures to a second region of the image plane in which the second FOV is different from the first FOV, and the second region of the image plane is different from the first region of the image plane. A third region of nanostructures directs a third FOV of light to a third region of the image plane, in which the third FOV is different from the first FOV and the second FOV, and the third region of the image plane is different from the first region and the second region of the image plane.

摘要： An active metasurface that provides low-loss and high-bandwidth modulation control of light includes a number of cells arranged on a substrate. A controller dynamically alters a voltage differential supplied to the electrodes of each of the cells is adapted to alter refractive index of each of the high-index dielectric blocks in order to controllably steer light exiting the cell.

摘要： A method for preparing a metal-dielectric strip array based super-resolution lens includes: performing lithography on a first material layer on a first substrate to obtain a grating structure; alternately depositing second and third material layers until the grating structure is filled up, to obtain a first transition structure, one of the second and third material layers being of metal, and the other one being of dielectric; performing planarization on the first transition structure at least reach the top of the grating structure, to obtain a second transition structure; adhering an upper surface of the second transition structure to a second substrate; removing the first substrate, and performing overturning to make the second transition structure be on the second substrate to obtain a third transition structure; and performing planarization again to at least reach the top of finally deposited second or third material layer, to obtain the super-resolution lens.

摘要： A metasurface device may include a metasurface including multiple metasurface elements configured to receive light including at least one of a first polarization or a second polarization with a diverging wavefront from a light source. The first polarization and the second polarization may be orthogonal. The metasurface elements may include an interior metasurface element which is substantially aligned to an axis and exterior metasurface elements which are rotated with respect to the axis. The exterior metasurface elements positioned farther away from the interior metasurface element may be more rotated than the exterior metasurface elements positioned closer to the interior metasurface element. The metasurface may be configured to diffract light with the first polarization into a first output light beam and/or light with the second polarization into a second output light beam.

摘要： A dot pattern projector and its associated method of manufacture. The dot pattern projector utilizes VCSEL diodes that shine infrared light through a transparent layer. The VCSEL diodes can be formed directly onto the transparent layer or onto a substrate that is in contact with the transparent layer. The VCSEL diodes are lithographically formed into a matrix, wherein each of the VCSEL diodes shines a cone of infrared light into and through the transparent layer. Each cone of infrared light intersects at least one other cone of infrared light within the transparent layer. A dielectric layer covers the transparent layer. The dielectric layer reduces reflections at the second surface of the transparent layer. A metasurface is formed on the dielectric layer. The metasurface converts the light passing through the dielectric layer into a specific dot pattern or other such pattern.
