SmartScan: Simulation-Based Detection of a Laser Processing Scanner System

The project focuses on the simulation aspect of the overall project. It demonstrates that realistic calculations for both temperature distribution and deformation behavior in a lens system are feasible. The model relies on known parameters like geometry and material properties, supplemented by irradiation experiments to determine laser heat input and heat transfer coefficients.

The “Equivalent Heat Source” method, adapted from welding simulations, accurately models laser-induced heat distribution, validated by experiments conducted by partners TU Ilmenau and FH Jena. Results show that heat input primarily affects the lens surface, with equilibrium determined by heat dissipation, tested by Optris. Mesh density recommendations balance computational efficiency and result quality. Deformation analysis aligns with experimental findings, aiding in focus shift evaluation. The project also explores representing multi-lens systems with a single equivalent element, illustrating its application and limitations.
