In precision laser technology, laser scanning galvanometers are undeniably the core execution unit. From millimeter-level industrial marking to micron-level additive manufacturing, scanning galvanometers, with their unparalleled speed and precision, have become a key force driving technological advancement.
However, for most engineers engaged in laser application development, scanning galvanometers are both familiar and mysterious. When laser additive manufacturing faces corner burnout, how can we eliminate it at the control level? When achieving seamless processing on large workpieces, why does the traditional "step-and-scan" method introduce stitching errors, and how does "in-scope field of view" (IFOV) technology address this issue? Why are small-aperture galvanometers extremely fast, while large-aperture galvanometers are relatively slow? What core physical contradictions lie behind this? ...
