CONCENTRIC ARCHITECTURE FOR OPTICAL SENSING

This abstract first appeared for US patent application 20240407659 titled 'CONCENTRIC ARCHITECTURE FOR OPTICAL SENSING

Original Abstract Submitted

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.
