title: Combination of multiple light paths in pulse oximetry: the finger ring example.
abstract: When pulse oximetry is required at other body locations than the finger tip new strategies for optical setups and signal handling are required. In this paper we present a combination of short and long light paths that succeeded in resolving the problems associated to the development of a finger ring SpO2 sensor.
