Working principle

According to the principle that the absorption rate of near-infrared light of deoxyhemoglobin in venous blood is different from that of other tissues, the subcutaneous blood vessels are projected on the skin surface in situ by a series of means, such as infrared back light scattering image collection micro projection technology. In order to achieve a clear display of subcutaneous blood vessels.
