Abstract: Systems, devices, and methods for tracking one or more physiological metrics (e.g., heart rate, blood oxygen saturation, and the like) of a user are described. For example, one or more light sources and one or more light detectors may be positioned on a wearable device such that light can be emitted towards the user's skin and further such that light reflected back to the wearable device can be measured and used to generate values for the one or more physiological metrics.

Abstract: Structures and techniques are provided for shaping or steering a light field for an optical biological parameter sensor such that the light is partially or wholly collimated and enters a person's skin at an oblique angle to the person's skin such that the light has a direction component oriented towards or away from a photodetector of the optical biological parameter sensor.
