    Abstract: 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 a plurality of pixel arrays, each of the which is associated, respectively, with a different one of a plurality of optical channels configured for detection of incoming light rays of a particular wavelength or a particular range of wavelengths centered on the particular wavelength. 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 monochromatic image. Methods of operation are described as well.

    Abstract: An apparatus in some implementations includes a metalens, an image sensor, and an actuator. The metalens is configured 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.

    Abstract: 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.

    Abstract: An apparatus includes a metalens, an image sensor, and an actuator. The metalens is configured to generate multiple diffractive orders of an image at respective corresponding focal lengths. The actuator operable to move at least one of the metalens or the image sensor to each of a various positions so that a distance between the metalens and the image sensor is adjusted, wherein 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. Adjusting the distance between the metalens and the image sensor provides a zoom in or zoom out operation.
