Abstract:
1. A method of monitoring a subject via a sensor module, wherein the sensor module includes at least one optical emitter and at least one optical detector, a first light guide having a proximal end optically coupled to the at least one optical emitter and an opposite distal end with a free end surface, and a second light guide having a proximal end optically coupled to the at least one optical detector and an opposite distal end with a free end surface, the method comprising: attaching the sensor module to a body of the subject such that the respective distal end free end surfaces of the first and second light guides engage respective portions of the body of the subject; delivering light from the at least one optical emitter directly into the body of the subject via the distal end free end surface of the first light guide; and collecting light directly from the body of the subject via the distal end free end surface of the second light guide.
