Abstract: The invention discloses a method for production of laser-induced images with internal structure, so as its internal structure is visible. The method provides the creation of the arrangement of laser-induced damages so that: the outer laser-induced damages do not shade the internal laser-induced damages; all laser-induced damages are located inside 3D image space and reproduced both internal shapes of separate fragments and their shades of gray; all laser-induced damages can be produced by laser-induced breakdown without internal crash of a transparent material. The method can be used for producing both art and tomographic images.

Abstract: A method for creating 3D laser-induced head image inside transparent material is disclosed. Initial information for this creation is several 2D portraits. Creation of 3D laser-induced head image has three stages. The first stage is the construction of 3D head model from corresponding principal parts detailed from given 2D portraits and creation of the bearing point arrangement by covering the model by equidistance points. This bearing point arrangement gives information only about spatial configuration of points. The second stage is transformation of the bearing point arrangement into point arrangement, which has more complete information about portraits. The third stage is production of a plurality of the etch points inside a transparent material by a laser beam, which is periodically focused at the points belonging to the transformed point arrangement.
