摘要：
An optical measurement module is disclosed that includes three or more recessed regions separated from each other by two or more barrier walls, the recessed regions including at least two distal recessed regions. The optical measurement module may also include first and second photo-emitter elements that emit light in different spectrums and first and second photodetector elements. One or more of the second photo-emitter elements may be located in one of the distal recessed regions, and the second photodetector element may be located in one of the other distal recessed regions. The first photodetector element may be located in a recessed region other than the recessed region where the second photodetector element is located, and the one or more photo-emitter elements may be located in one of the recessed regions other than the one where the first photodetector element is located.
