For non-invasive measurement of blood glucose, we proposed an ATR absorption spectroscopy system using a QCL with a MEMS-based external cavity that enables a rapid sweep of emitting wavelength. By using this system, we measured absorption of human lip mucosa and as a result, we observed that the change of the peak intensity follows that of blood glucose well and we confirmed the correlation between the peak intensity and blood glucose level.
