Laser Marking in Digital Encoding of Surfaces

Abstract:

Article Preview

In this work we consider some laser based methods and technologies for surface engraving and layered marking of opaque and transparent materials. Based on that, physical object surface and sub-surface layers can be enhanced with digital codes for augmented security and more advanced human-computer interactions. Laser procedures for creating digitally encoded layers in various materials are investigated and one of the mechanisms of laser-induced formation of marks (micro-cracks) in transparent materials is discussed in more details.
