Diabetes is one of the biggest health challenges in human beings in 21st century. Determination of blood glucose level is a frequently occurring procedure in diabetes care. As the most common method involves collecting blood drops for chemical analysis, it is invasive and liable to afflict a degree of pain and cause a skin injury. To eliminate these disadvantages, this project focuses on pulsed photo acoustic techniques, which have potential ability in non-invasive blood glucose measurement. The fundamental theory of photo acoustics in liquid and soft tissue will be studied systematically. The distributions of photo acoustic sources in a near-infrared optical skin model can be simulated by the Monte Carlo method. Expansion coefficient and specific heat of glucose solution will be measured by thermodynamic method, while the sound velocity in it can be determined by photo acoustic approach.The effect of glucose on blood optical scattering can be studied by a picosecond pulsed laser. A photo acoustic apparatus comprising a pulsed laser diode and a piezoelectric transducer can be built and applied to measure glucose concentration in water and scattering media. Moreover, this apparatus can be used to non-invasive experiment on human fingers.
