Abstract
The invention relates to a method and a device for in vivo detection of the direction of Langer's lines in the skin. Light is irradiated into the skin as primary light at one defined site ( ) identified through the epidermis ( ) in such a way that it is transported in the skin ( ) by scattering or absorption, while part of said irradiated light emerges from the skin as secondary light in the region surrounding the irradiated site. An amplitude-dependent property of secondary light emerging from the skin ( ) around the irradiated site is measured in order to determine the preferential direction of the diffuse light transport in the skin ( ) and, consequently, determine the orientation of Langer's lines thereof.
