Abstract

The noninvasive determination of blood and tissue parameters is a promising application of photoacoustic laser spectroscopy. Optical absorption spectra of human whole blood in the visible and near infrared spectral region were measured using the photoacoustic response produced by modulated diode lasers. As glucose is one of the most important blood parameters, the aim of our investigations is the development of a sensor system which is suitable for continuously noninvasive monitoring of blood glucose concentrations in diabetic patients.
