" This study is to present a new scheme for the detection of human meridian system non-invasively. The optical transport properties along the pericardium meridian and a non-meridian path about 1 cm away from the meridian were measured non- invasively on 20 healthy people in vivo. 633 nm, 658 nm and 785 nm red lasers were used for irradiation, and the diffuse light emittances at different points on meridian and non-meridian directions were collected respectively and compared. Our study suggested that the light propagation characteristics along both the meridian and non-meridian directions conformed to the Beer's exponential attenuation law. Statistical analysis of the results suggested that the optical properties of human meridian differ from those of the surrounding tissue (p < 0.05), and the light attenuation is less when propagating along the pericardium meridian than along the non-meridian direction. These findings not only confirmed the objective existence of acupuncture meridians, but also shed new light on the understanding of meridians."
