Abstract: This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The system (1700) includes a light source (1702) configured to output light to a sample (1720);
a first output region (1793) located at an interface of the system and configured to receive a first light from a first location within the sample;
a second output region (1995) located at the interface of the system and configured to receive a second light from a second location within the sample;
a detector (1730); and
an optics unit (1712, 1719, 1723, 1729), comprising:
first optics configured to receive the first light from the first output region and direct the first light from the first output region to the detector; and
second optics configured to receive the second light from the second output region and direct the second light from the second output region to the detector.
