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.所揭示的係一種包括具有同心架構之光學感測的電子裝置及其操作方法。該同心架構可包括圍繞（多個）光發射器以同心方式配置的（多個）光偵測器。在一些實例中，至少一光發射器可經定位於該裝置中心，且各光偵測器可經定位距離該光發射器相同的分開距離處。各光偵測器可經配置使得距離該經定位於中心之光發射器的該分開距離可大於距離另一光發射器的分開距離。本揭露的實例進一步包括一選擇性透明層，其覆疊該（多個）光偵測器。該選擇性透明層可包括（多個）區段，其等對一第一波長範圍透明且對一第二波長範圍不透明。在一些實例中，該選擇性透明層可進一步包括對該第二波長範圍透明的（多個）區段。
