Claim 0:
1. An apparatus for estimating body temperature, the apparatus comprising:
a spectrometer comprising a detector and at least two light sources that are spaced apart from the detector by different distances, and configured to obtain a spectrum through a plurality of light paths between the at least two light sources and the detector through a tissue underneath a surface of an object;
a temperature sensor configured to measure a surface temperature from the surface of the object; and
a processor configured to:
determine temperature differences that minimize differences between the spectra of the plurality of light paths and a reference spectrum measured at the surface temperature, respectively,
obtain a temperature slope based on the temperature differences that minimize the differences between the spectra of the plurality of light paths and the reference spectrum; and
estimate the body temperature of the object based on the temperature slope.
