Abstract: A vector model representing laser beam propagation into a two-axis laser scanhead is proposed. The model based on mathematical principles is classified as a stochastic model in which at least one of the input or output variables is probabilistic. The purpose of the model is to understand the behaviour of the scanhead system particularly in relation to the errors incurred from its design and the laser beam. Using this model, simulation looks into reproducing the marking results of a commercially available scanhead, effects of aperture misalignment, 3D ray tracing and Gaussian beam relations.
