    Abstract: An electronic device including optical sensing with a concentric architecture and methods for operation thereof is disclosed. The concentric architecture can include light detector(s) arranged in a concentric manner around light emitter(s). In some examples, at least one light emitter can be located in the center of the device, and each light detector can be located the same separation distance from the light emitter. Each light detector can be arranged such that the separation distance from the centrally located light emitter can be greater than the separation distance from another light emitter. Examples of the disclosure further include a selective transparent layer overlaying the light detector(s). The selective transparent layer can include section(s) transparent to a first wavelength range and non-transparent to a second wavelength ranges. In some examples, the selective transparent layer can further include section(s) transparent to the second wavelength range.

    Abstract: An electronic device can include a housing that includes an optically transparent component. First and second light emitters can be positioned in the internal volume defined by the housing. A light detector can be positioned in the internal volume and can be optically isolated from the first and second light emitters within the internal volume. An opaque material can be disposed on the optically transparent component and can be positioned to inhibit light emitted from the second light emitter from reaching the light detector and to allow light emitted from the first light emitter to reach the light detector.

    Abstract: This relates to an electronic device configured for optical sensing having shared windows and including light restriction designs. The light restriction designs can include one or more of optical layers, optical films, lenses, and window systems configured to reduce or eliminate crosstalk between optical components. A plurality of accepting sections and a plurality of blocking sections can be employed to selectively allow light having an angle of incidence within one or more acceptance viewing angles and block light with angles of incidence outside of the acceptance viewing angles. In some examples, the light restriction designs can include variations in optical and structural properties can allow the light restriction designs to have spatially varying acceptance angles. Variations in structural properties can include, but are not limited to, differences in widths, heights, and/or tilts of the accepting sections and/or blocking sections.

    Abstract: An electronic device may have an optical sensor such as an ambient light sensor for detecting ambient light. The ambient light sensor may include one or more photodetectors and light control layers disposed over the photodetectors. The light control layers may include light control structures forming concentric strips of opaque or light absorbing material. The light control layers may include one layer of light control structures, two layers of light control structures, or three or more layers of light control structures separated by one or more intervening transparent substrates. The electronic device may include associated control circuitry configured to compute angular information on the ambient light based on readings output from the one or more photodetectors.

    Abstract: An electronic device may include sensors such as a visible-light image sensor for capturing images. The sensors may also include optical sensors that operate at other wavelengths. An infrared light sensor may be used to gather an infrared light spectrum of a target object. The infrared light sensor may have a beam steerer and other adjustable components such as adjustable lenses and adjustable polarizers. During operation, an infrared beam emitted by the infrared light sensor may be steered onto the target object using information from a captured visible-light image and/or other sensor data such as distance sensor data, orientation sensor data, three-dimensional image sensor data, and data from other sensors. Infrared spectra, visible-light camera images, and/or data from other sensors may be used in characterizing target objects so that notifications can be provided to a user and other actions taken.

    Abstract: An electronic device may have a display with an array of pixels that display images for a user. The electronic device may have an ambient light sensor for gathering ambient light information. A subset of the pixels in the array of pixels may overlap the ambient light sensor so that ambient light passing through the subset of pixels may be measured. Each pixel may have an emission enable transistor coupled in series with a light-emitting diode. Control circuitry in the electronic device may disable the subset of pixels to reduce stray light during ambient light measurements while enabling remaining pixels in the array of pixels to display an image. Ambient light sensor circuitry may gather ambient light sensor measurements over one or more periods by using transfer transistors to transfer change from the photodetectors to charge storage capacitors formed from floating diffusions in a common substrate.
