    Abstract: Systems and techniques are provided for imaging with a meta-lens. For instance, a process can include receiving light at a first substrate, the first substrate comprising a first meta-lens; receiving a first portion of the light at a second substrate, the second substrate including an optical sensor, wherein: the optical sensor is directly covered by a solid covering, and the first substrate is mechanically coupled to the second substrate such that the solid covering is between the first substrate and the second substrate; and receiving, by the optical sensor and through the solid covering, at least a second portion of the light focused by the first meta-lens.

    Abstract: Techniques and systems are provided for high resolution time-of-flight (ToF) depth imaging. In some examples, an apparatus includes a projection system including one or more light-emitting devices, each light-emitting device being configured to illuminate at least one portion of an entire field-of-view (FOV) of the projection system. The entire FOV includes a plurality of FOV portions. The apparatus also includes a receiving system including a sensor configured to sequentially capture a plurality of images based on a plurality of illumination reflections corresponding to light emitted by the one or more light-emitting devices. Each image of the plurality of images corresponds to one of the plurality of FOV portions. An image resolution associated with each image corresponds to a full resolution of the sensor. The apparatus further includes a processor configured to generate, using the plurality of images, an increased resolution depth map associated with the entire FOV.

    Abstract: Systems and techniques are described for depth sensing. For example, a method can include obtaining a first depth image of a scene. The first depth image of the scene is associated with a first illumination configuration including illuminating the scene with a first type of illumination. The method can include obtaining a second depth image of the scene, wherein the second depth image is associated with a second illumination configuration, different from the first illumination configuration. The second illumination configuration includes illuminating the scene with a second type of illumination. The method can include determining, based on the second depth image, multipath interference (MPI) associated with the first depth image. The method can further include generating based on determining the MPI associated with the first depth image an adjusted depth image including one or more pixels from the first depth image and one or more adjusted pixels.

    Abstract: Aspects of the present disclosure relate to an image sensor. An example apparatus includes an image sensor including one or more pixels. Each pixel of the one or more pixels includes a photodetector, and the photodetector includes a photosensitive surface including germanium. In some implementations, the photodetector includes a photodiode including an intrinsic silicon layer doped with germanium or including germanium crystals. The intrinsic layer may be between a p− layer and an n− layer not including germanium. The intrinsic layer may be configured to absorb photons of the light received at the intrinsic layer. The light may include one or more reflections of an emitted light for active depth sensing. For example, the emitted light may be frequency modulated and having a first wavelength for indirect time-of-flight depth sensing. Sampling circuits may generate voltages indicating a phase difference between the emitted light and a reflection of the emitted light.

    Abstract: Systems and techniques are described for large field of view digital imaging. A device's first image sensor captures a first image based on first light redirected from a first path onto a redirected first path by a first light redirection element, and the device's second image sensor captures a second image based on second light redirected from a second path onto a redirected second path by a second light redirection element. A virtual extension of the first path beyond the first light redirection element can intersect with a virtual extension of the second path intersect beyond the second light redirection element. The device can modify the first image and second image using perspective distortion correction, and can generate a combined image by combining the first image and the second image. The combined image can have a larger field of view than the first image and/or the second image.
