METHOD OF LASER FORMATION OF THE THREE-DIMENSIONAL IMAGES IN FIRM OPTICAL ENVIRONMENTS

摘要

The invention concerns to technologies of reception of the three-dimensional images in firm optical environments with help of a laser beam, and can find application in various industries for creation of the images in volume of a material. The offered way is carried out by creation of volumetric discrete fragments, its centres are removed from each other on distance not less than two sections of such fragments. Creation of volumetric discrete fragments carry out with the help of a laser beam with parameters: density of capacity - exceeding threshold means of penetration (piercing) of a firm optical material, for example for a glass DOLLAR Kgr;-8-5 10<11> Vt/cm<2> and duraction of a pulse 5 10<-7> sec. Thus formation of discrete fragments is carried out on distance not less than 1 mm from the surface of the unit, firm optical environment - external environment, and focusing of radiation in volume of firm optical environment on axis Z is determined as F n, where F - focal length in vacuum, n - coefficient of refraction of used firm optical environment. Formation of volumetric discrete optical fragments is carried out by moving firm optical environment in three mutually prependicular planes relevantly to a laser beam under the given law. The offered method provides reception of the three-dimensional images in volume of firm optical environment with situation of the separate discrete points on three planes is equivalently as well as at initial object, at prevention of destruction of firm optical environment at the expense of spontaneous formation of cracks between volumetric discrete fragments.
