Abstract
We investigated a non-contact imaging method to evaluate plethysmogram and vasomotion with a digital color camera. Monte Carlo simulation for light transport in skin tissue is used to specify a relation among the red-green-blue-values and hemoglobin contents. Applying the FFT band pass filters to each pixel of the sequential images for the total hemoglobin concentration along the time line, two-dimentional plethysmogram and vasomotion can be reconstructed. In vivo experiments with human skin before, during, and after auditory stimulation demonstrated the feasibility of the method to evaluate the activities of autonomic nervous systems.
