    Abstract: An electronic device may include an optical image sensor that includes an array of optical image sensing pixels and a pin hole array mask layer above the optical image sensor and that includes spaced apart pin holes therein defining spaced apart image areas on the optical image sensor. The electronic device also includes a display layer above the pin hole array mask layer that includes spaced apart display pixels. The electronic device may also include processing circuitry coupled to the optical image sensor and capable of sensing images from spaced apart sub-arrays of the array of optical image sensing pixels aligned with the spaced apart image areas.

    Abstract: An apparatus for fingerprint sensing includes a light-emitting layer, an optical layer, a filter layer and a pixelated image sensor. The light-emitting layer is covered by a transparent layer, and can illuminate a surface touching the transparent layer and allows transmission of reflected light from the surface to the optical layer. The optical layer includes a plurality of optical elements. The filter layer includes a number of apertures and spatially processes the reflected light. The pixelated image sensor can sense the spatially processed light. At least one of the optical layer or the filter layer enables an angle-focused FOV filtering of the reflected light.

    Abstract: A method of authenticating a user of a wearable electronic device includes emitting light into a dorsal side of a forearm near a wrist of the user; receiving, using a light field camera, remissions of the light from the dorsal side of the forearm near the wrist of the user; generating a light field image from the remissions of the light; performing a synthetic focusing operation on the light field image to construct at least one image of at least one layer of the forearm near the wrist; extracting a set of features from the at least one image; determining whether the set of features matches a reference set of features; and authenticating the user based on the matching. In some embodiments, the method may further include compensating for a tilt of the light field camera prior to or while performing the synthetic focusing operation.

    Abstract: Systems and methods for through-display imaging. A display includes an imaging aperture defined through an opaque backing. An optical imaging array is aligned with the aperture. Above the aperture, the display is arranged and/or configured for increased optical transmittance. For example, a region of the display above, or adjacent to, the imaging aperture can be formed with a lower pixel density than other regions of the display, thereby increasing inter-pixel distance (e.g., pitch) and increasing an area through which light can traverse the display to reach the optical imaging array.

    Abstract: An acoustic imaging system includes multiple acoustic transducers disposed to circumscribe a portion of imaging surface. An acoustic imaging system also includes a controller and an image resolver. The acoustic transducers convert electrical signals into mechanical energy and/or mechanical energy into electrical signals. The controller is adapted to apply an electrical signal to the acoustic transducers which, in response, induce a mechanical wave, such as a surface wave, into the circumscribed portion. The controller is also adapted to receive electrical signals from the acoustic transducers. The image resolver uses the electrical signals received by the controller in order to construct an image of an object in physical contact with the imaging surface.

    Abstract: An acoustic imaging system can include an array of transducers in acoustic communication with a substrate configured to receive a subject for imaging. The transducers can independently or cooperatively send an acoustic pulse into the substrate toward the subject. In many examples, a number of adjacently-positioned transducers are activated substantially simultaneously so as to generate a plane wave into the substrate. After the plane wave has had an opportunity to propagate through the substrate, reflect from the top surface, and propagate through the substrate again, the electrical signals can be obtained from the transducers and an image of the subject can be assembled. In many embodiments, the plurality of transducers can be driven and read in groups such as non-intersecting (disjoint) sets or subarrays.
