1. An apparatus for measuring body core temperature comprising:

  • a light guide comprising an internally reflective tube, the light guide coupled to an earpiece, the light guide having a first end and a second end;

    a first sensor positioned at the first end of the light guide;

    a second sensor positioned at the second end of the light guide; and

    a processor coupled to the first sensor and the second sensor;

    wherein the first sensor is operable to sense infrared radiation from an infrared source at the second end of the light guide;

    wherein the second sensor is operable to measure a temperature of the light guide at the second end of the light guide; and

    wherein the processor is operable to determine a temperature of the infrared source at the second end of the light guide by compensating for infrared radiation due to a thermal gradient of the light guide via a regression analysis across a range of ambient temperatures of the light guide.
