Extensive research has shown the fluence within the range of 0. In addition to the total concentration of hemoglobin, the oxygen saturation will define the concentration of oxy and deoxyhemoglobin in tissue and so the total absorption spectrum. Open in a separate window. J Phys D Appl Phys. Poor penetration of infra-red and helium neon low power laser light into the dermal tissue. Video abstract Click here to view. No energy could be detected penetrating either human skin or sheep skin from a commercially available 0. Our recent tissue studies demonstrate no penetration of low level NIR energy through 2 mm of skin or 3 cm of skull and brain. Such low-frequency features centered around 60 cm -11.
