Design of a beam-expander for the large-area profile measurement
碩士 === 國立成功大學 === 物理學系 === 102 === In this article, a beam expander is designed to transform a Gaussian laser beam into a collimated and uniform large-area illumination. The system exploits two freeform lenses to reach the goal, and has a solution for the over-thickness of the lenses. To close out,...
