Biomimetic structures for mechanical applications by interfering laser beams: More than solely holographic gratings
Published online by Cambridge University Press: 01 August 2006
Abstract
A variety of biological materials composed of hierarchical phase composites can be found. These biological materials successfully combine impressive toughness with high stiffness and strength. Deposition techniques combined with high-power laser beams can imitate biological structures in technical systems. Interference phenomena, such as surface scattering, Lloyd's mirror arrangements, or interference of coherent beams, can be used to create these biomimetic long-range ordered structures on the scale of nanometers to micrometers. These structures are not limited to topographic texturing, as in the case of holographic gratings; rather, they can also create composite structures and phase transformations. This article presents a brief overview of interference techniques, their possibilities, and their limits.
