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: Systems and techniques are described for large field of view imaging. A device's first image sensor captures a first image based on first light from a scene redirected by a light redirection element (e.g., a first prism and/or first reflective surface), and the device's second image sensor captures a second image based on second light from the scene redirected by the light redirection element (e.g., a second prism and/or second reflective surface). The device can modify the first image and/or second image using perspective distortion correction and/or to align one or more properties of two respective depictions of a shared portion of a scene in the two images. The one or more properties can include brightness, contrast, positioning, sharpness, tint, hue, and/or saturation. The device can generate a combined image with a large field of view and smooth transitions by combining the first image and the second image.

Abstract: Systems and techniques are provided for meta-lens cameras. For example, an apparatus can include a first substrate including a first aperture and a second substrate including a first meta-lens. The first substrate and the second substrate are mechanically coupled such that at least a first portion of the first aperture is disposed over at least a second portion of 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: Aspects of the present disclosure relate to a device for active depth sensing with an adjustable distribution of light projected. An example device includes a light projector. The light projector includes a light source configured to emit a light and a diffractive element. The diffractive element includes a first diffractive optical element having a first refractive index and configured to project a first distribution of light, a second diffractive optical element having a second refractive index and configured to project a second distribution of light based on a refractive material between the first diffractive optical element and the second diffractive optical element, and the refractive material located between the first diffractive optical element and the second optical element. The refractive material is adjustable to have a second refractive index for the first mode and a third refractive index for the second mode.

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: Systems and techniques are described for controlling digital imaging field of view. A device's first image sensor captures a first image based on first light redirected by a light redirection element, and the device's second image sensor captures a second image based on second light redirected by the light redirection element. The device can modify the first image and second image using perspective distortion correction, and can generate a combined image with a large field of view by combining the first image and the second image. The light redirection element can include two prisms that have corners cut and polished to form edges, which can be coupled together and/or colored. A refractive index of the adhesive can be selected to minimize light noise in the combined image. A light-absorbent colorant can coat the interface between the edges of the prisms to minimize light noise in the combined image.

Abstract: Various embodiments are directed to an image sensor that includes a first sensor portion and a second sensor portion. The second sensor portion may be positioned relative to the first sensor portion such that the second sensor portion may initially detect light entering the image sensor, and some of that light passes through the second sensor portion and may be detected by the first sensor portion. In some embodiments, one more optical filters may be disposed within the image sensor. The one or more optical filters may include at least one of a dual bandpass filter disposed above the second photodetector or a narrow bandpass filter disposed between the first photodetector and the second photodetector.

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.
