Laser Fabrication of Holograms on Carbon Fiber Reinforced Polymers - SISMA %


The University of Patras, in collaboration with SISMA, has presented a new research work at the Conference on Lasers and Electro-Optics (CLEO) 2022.

In this work, holographic optical elements (HOE) are fabricated on the surface of mirror-polished Carbon Fiber Reinforced Polymers (CFRP) using a UV industrial laser.

Laser engraving is limited to the covering top resin, with no structural damage of the underneath fiber mesh. The high quality of the engraving is verified using both analogue and digital reconstruction. Apart from elaborating the surface laser processing technology to CFRP, our results demonstrate the potential of the proposed method for traceability and authentication of CFRP.
