Abstract
The goal of this study was to analyze temperature dependent changes in NIR reflectance of ex vivo freshly excised human skin. A broadband halogen lamp was used as a light source. Remitted light was collected using an optical fiber and analyzed by a grating spectrometer. Samples were heated to and maintained at temperatures up to 60°C using a temperature control unit. The temperature was also independently monitored using a thermal camera. Consistent changes found include blue shift in water absorption peaks. This method may prove to be useful for monitoring tissue temperature during clinical procedures in real time.
