Abstract
This is a presentation of commercially available galvanometric and resonant oscillatory scanners. It is intended to assist in the selection of component, single and multi-axis scanning arrangements. The features of galvanometric scanners are reviewed and figures of merit offered to rate electromagnetic drivers. Position transducers are examined and three capacitive sensors compared. Resonant scanners are analyzed with a presentation of the milestones to be resolved by commercial product manufacturers. Multi-axis scanning arrangements are examined and the distortions of four configurations reviewed. The last section has 11 tables grouping comparable commercial products. A list of manufacturers is offered.
