Noninvasive monitoring of glucose and other biological compounds with a thermal wave assisted technique

Combining thermal wave techniques with conventional optical detection methods, such as absorption, reflection, scattering or polarimetry, may significantly improve the ability to perform noninvasive monitoring of glucose and other biological compounds. These improvements arise from the attributes of thermal wave technology to spatially localize the measurement to the appropriate region in the tissue or bloodstream, and to substantially reduce other sources of background signal and noise.
