BODY CORE TEMPERATURE MEASUREMENT

摘要

A device for measuring body core temperature includes a light guide. The light guide is coupled to an earpiece. A first sensor is positioned at a first end of the light guide, and a second sensor is positioned at a second end of the light guide. A processor is coupled to the first sensor and the second sensor. The first sensor senses infrared radiation from an infrared source at the second end of the light guide, and the second sensor measures a temperature of the light guide at the second end of the light guide. The processor determines 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.
