Abstract
Systems and methods directed to the assessment of circulatory complications due to advancement of diabetes. Embodiments include an optical measurement device having a light source with one or more wavelengths and configured to illuminate an area of tissue, a detector configured to capture the light reflecting from one or more layers of the tissue at the one or more illumination wavelengths, a processor configured to compute, based on the detected signal of layer extracted circulatory data, one or more estimates of tissue vascular health, and a display or communication device (e.g., electronic data transfer) configured to store or report the tissue vascular health. In exemplary embodiments, the distribution of chromophores such as hemoglobin in different layers of skin is extracted using a combination of structured light in the visible and near-infrared regime.
