    Abstract: This relates to systems and methods for determining one or more of a user's physiological signals. The one or more of the user's physiological signals can be determined by measuring pulsatile blood volume changes. Motion artifacts included in the signals can be canceled or reduced by measuring non-pulsatile blood volume changes and adjusting the signal to account for the non-pulsatile blood information. Non-pulsatile blood volume changes can be measured using at least one set of light emitter-light sensor. The light emitter can be located in close proximity (e.g., less than or equal to 1 mm away) to the light sensor, thereby limiting light emitted by the light emitter to blood volume without interacting with one or more blood vessels and/or arterioles. In some examples, the systems can further include an accelerometer configured to measure the user's acceleration, and the acceleration signal can be additionally be used for compensating for motion artifacts.

    Abstract: An electronic device can include a housing defining an aperture, and an electromagnetic radiation emitter and an electromagnetic radiation detector disposed in the housing. An optical component can be disposed in the aperture and can include a first region of a first material having a first index of refraction, the first region aligned with the electromagnetic radiation emitter, a second region of the first material, the second region aligned with the electromagnetic radiation detector, and a bulk region surrounding a periphery of the first region and a periphery of the second region, the bulk region including a second material having a second index of refraction that is lower than the first index of refraction.

    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.
