    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: 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 so that the light restriction designs 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.
