Abstract
A wearable module for use in an optical measurement system includes a housing including a top surface, a light guide including a distal end portion adapted to protrude from the top surface of the housing, and a spring member configured to bias the distal end portion of the light guide away from the top surface of the housing. The light guide is configured to receive, at the distal end portion, photons from a light pulse scattered by a target within a body of a user and guide the received photons toward a photodetector.
