Photoacoustic Measurement and Experiment of Glucose Concentrations in an Aqueous Matrix

Abstract:

In the near-infrared region, we can test the blood glucose by non-invasive method. Based on this theory, combined photoacoustic principle, we had research about the simulated samples of blood glucose, measured the concentration of glucose solution. We have discussed the optimal wavelength in the near-infrared region (780-2400nm), and did the experiment repeatedly, and then analyzed data through the linear, polynomial and exponential fitting of the Generalized Least Squares, the measuring accuracy of the glucose solution had improved. These research results provide the guidance on the practice and experimental evidence for the further research of measuring.
