Design of an optical refocusing illumination system for use in laser-scanning devices Vrije Universiteit Brussel
Optical laser-scanning systems generally contain a scanning lens, like an f-Theta lens, to enable a planar imaging field. However, commercially available f-Theta lenses show limited working distances and scan fields, while their lens diameter rapidly scales with the scanning range giving rise to bulky lens systems. Therefore, we propose a novel scanning lens configuration, based on a compact tunable lens system, generating a planar imaging ...
