The Research of Glucose Solution Based on Photoacoustic Measurement

Abstract:

Based on the principle of photoacoustic,blood glucose can be non-invasive monitoring of in the NIR region.The system irradiates to the glucose solution by opo laser,then the signals are received by photoacoustic probe and processed by the oscilloscope, finally imported into the computer.By the least squares method,the data repeatedly fits to make the mean square error of the glucose concentration less than 5mg/dl.The experimental results show that:photoacoustic measurement method can achieve a certain precision, with the value of further research.
