Abstract
An apparatus for measuring body core temperature includes a light guide with an internally reflective tube. The light guide is coupled to an earpiece, and has a lens or an aperture positioned at one of its ends. A sensor is positioned at the other end of the light guide, and a processor is coupled to the sensor. The sensor senses infrared radiation from an infrared source at the end of the light guide, and the processor determines a temperature of the infrared source at the end of the light guide via a transfer function that correlates a measure of the infrared radiation observed by the sensor and an effect of radiation of the light guide.
