Abstract

Un método para proveer a un cuerpo de material con un marcado de sub-superficie que comprende pasos de dirección hacia una superficie del cuerpo, de un haz de alta densidad de energía al cual el material es transparente y dirigir el haz a un foco en un espacio localizado desde la superficie y dentro de un cuerpo de causando la ionisación localizada del material y la creación de una marca en la forma de un área de opacidad incrementada substancialmente a la radiación electromagnética, sin un cambio detectable en la superficie.A method of providing a body of material with subsurface marking comprising directional steps towards a body surface of a high energy density beam to which the material is transparent and directing the beam to a focus on a localized space from the surface and within a body causing localized ionization of the material and the creation of a mark in the form of an area of opacity substantially increased by electromagnetic radiation, without a detectable change in the surface.
