Novel scanner designs
Jean I. Montagu · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2002
The speed of current microprocessors permits real time correction of galvanometer's imperfections and have become an integral elements of scanning systems. Consequently the critical parameters of scanning galvanometers have been reduced to speed, first mechanical resonance and power dissipation. This paper examines armature rigidity and the copper density of various coil designs. External fiducial sensors and capacitive pick-off imbedded fiducial sensors shall be reviewed.
