Abstract: An acoustic imaging system includes multiple transducers disposed to circumscribe a portion of substrate. An acoustic imaging system also includes a controller and an image resolver. The 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 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 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 substrate.

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: 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. An optical imaging sensor is positioned at least partially behind a display and is configured to emit visible wavelength light at least partially through the display to illuminate an object, such as a fingerprint or a retina, in contact with or proximate to an outer surface of the display. Surface reflections from the object traverse the display stack and are received and an image of the object can be assembled.

Abstract: An apparatus for fingerprint sensing includes a touch-display layer covered by a transparent layer. The touch-display layer can emit light to illuminate a finger surface touching the transparent layer. The touch-display layer is transparent to reflected light from the surface to underlying layers. The underlying layers include a collimator layer and a pixelated image sensor. The collimator layer can collimate the reflected light, and the pixelated image sensor can sense the collimated reflected light. The collimator can collimate the reflected light to enable a one-to-one imaging ratio between an area of the finger surface touching the transparent layer and an area of a corresponding image formed on the pixelated image sensor.
