摘要： An apparatus includes a sensor having one or more drift-field demodulation pixels and wavelength separating optical elements (WSOEs) such as metalenses and diffractive optical elements (DOEs). The WSOE can be configured such that when light is incident on a pixel, the light passes through the WSOE first and such that different wavelengths are focused by the WSOE on different spatial points in the associated pixel.

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： An optical device includes an array of light-emitting elements, including a first subset of light-emitting elements and a second subset of light-emitting elements. The first subset of light-emitting elements is configured to emit light having wavelength L1. The device includes a high refractive index material selectively disposed on the second subset of light-emitting elements and an array of optical elements positioned so as to be illuminated by the first subset of light-emitting elements and by the second subset of light-emitting elements. The optical elements are regularly arranged in a common plane at a pitch P, the common plane is located a distance D from the array of light-emitting elements, and P2≈2L1D/N, N being an integer greater than or equal to 1.

摘要： Manufacturing an optical device includes providing a substrate (102) having a polymeric layer (104) on a surface of the substrate, forming openings in the polymeric layer, and depositing a material in the openings to form meta-atoms (114, 214) of a first metastructure. Adjacent ones of the meta-atoms are separated from one another by polymeric material of the polymeric layer. Optical devices that include one or more metastructures in which meta-atoms are separated from one another by polymeric material are described, as are modules that incorporate the optical devices.

摘要： Methods of manufacturing an optical device can include, in some implementations, providing a substrate having a first polymeric layer on a surface of the substrate and a second polymeric layer on the first polymeric layer, forming first openings in the second polymeric layer to define an etch mask composed of material of the second polymeric layer, and etching to form second openings in the first polymeric layer, wherein locations of the second openings are defined by the etch mask. A material is deposited in the second openings to form meta-atoms of a first metastructure, wherein adjacent ones of the meta-atoms are separated from one another by polymeric material of the first polymeric layer. Optical devices including metastructures can be formed, where meta-atoms of the metastructure have a relatively high aspect ratio.

摘要： An apparatus in some implementations includes a metalens, an image sensor, and an actuator. The metalens is con-figured to generate multiple diffractive orders of an image at respective corresponding focal lengths. The actuator is operable to move at least one of the metalens or the image sensor to each of multiple positions so that a distance between the metalens and the image sensor is adjustable. The distance between the metalens and the image sensor for each respective one of the positions corresponds to a particular one of the focal lengths.

摘要： Illumination modules are operable, in some implementations, to project a homogenous diffuse illumination onto a scene. Some implementations allow different subsets of light emitting elements to be addressed independently so that they can be turned on (or off) at different times, which can facilitate multi-mode operation.
