1. A sensor comprising:

  • a sensor body adapted to operate in a reflectance mode;

    an emitter disposed on the sensor body, wherein the emitter is adapted to deliver a first light into a tissue;

    a detector disposed on the sensor body, wherein the detector is adapted to detect the first light; and

    at least one protrusion disposed on a tissue-contacting surface of the sensor body, wherein the at least one protrusion is adapted to reduce the amount of a second light impinging the detector at an incident angle substantially in-line with an imaginary axis connecting the emitter and the detector.
