    Abstract: 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.

    Abstract: A camera system includes two or more sensor arrays and an optical path. The sensor arrays are on the same sensor chip. Each sensor array includes the same field of view (FOV) as each other sensor array. The optical path includes a main lens and a metalens that are shared by each sensor array, and a microlens associated with each sensor array. The metalens splits incident light into different spectrums of light and directs each respective spectrum to a corresponding sensor array. The different spectrums of light include at least two of visible light, near infrared light, shortwave infrared and longwave infrared, and at least one sensor array includes single-photon avalanche diodes. The image processor that provides image processing, object recognition and object tracking and/or image fusion functionality may be on the same sensor chip as the sensor arrays.

    Abstract: A pixel for an image sensor includes a resistive microbolometer sensor portion, a visible image sensor portion, and an output path. The resistive microbolometer sensor portion outputs a signal corresponding to an infrared (IR) image sensed by the resistive microbolometer sensor portion. The resistive microbolometer sensor portion uses no bias current. The visible image sensor portion outputs a signal corresponding to a visible image sensed by the visible image sensor portion. The output path is shared by the resistive microbolometer sensor portion and the visible image sensor portion, and may be controlled to selectively output the signal corresponding to the IR image, the signal corresponding to the visible image, or a fused image based on the IR image and the visible image. The resistive microbolometer sensor portion may sense a near infrared image or a longwave infrared image.

    IPC: G02B5/30

    Abstract: An image sensor includes polarizing filters and spectral filters that provide on-chip simultaneous full Stokes polarization parameters (both linear and circular polarization) and multi/hyper spectral imaging. A polarizing filter polarizes incident light into a predetermined linear direction. The light-polarizing filter includes a wire grid and an array of phase-modulating nanostructures. The wire grid includes at least one wire that includes a series of metal-insulator-metal wire structures. The array of phase-modulating nanostructures is formed on the wire grid and changes a phase of the incident light a predetermined amount. A phase-modulating nanostructure is a high-dielectric-index nanostructure that changes of incident light based on a first width and a second width of the phase-modulating nanostructure in which the first width is perpendicular to the second width.

    Abstract: Optical spectrometers may be used to determine the spectral components of electromagnetic waves. Spectrometers may be large, bulky devices and may require waves to enter at a nearly direct angle of incidence in order to record a measurement. What is disclosed is an ultra-compact spectrometer with nanophotonic components as light dispersion technology. Nanophotonic components may contain metasurfaces and Bragg filters. Each metasurface may contain light scattering nanostructures that may be randomized to create a large input angle, and the Bragg filter may result in the light dispersion independent of the input angle. The spectrometer may be capable of handling about 200 nm bandwidth. The ultra-compact spectrometer may be able to read image data in the visible (400-600 nm) and to read spectral data in the near-infrared (700-900 nm) wavelength range. The surface area of the spectrometer may be about 1 mm2, allowing it to fit on mobile devices.
