Non-invasive blood glucose measurement by mid-infrared spectroscopy using hollow optical fibers

Yuji MATSUURA1

For non-invasive blood-glucose measurement, a mid-infrared spectroscopy system comprising hollow optical fibers and a multi-reflection attenuated-total-reflection (ATR) prism is developed. By using a Fourier-transfer infrared spectroscopy system, the absorption spectra of lip mucosa revealed clear signatures of glucose and measurement errors less than 20% were obtained. The result of a compact and low-cost measurement system using quantum cascade lasers is also shown.
