摘要：

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.
