Circular Scanning Resolution Improvement by its Velocity Close Loop Control

Laser scanning is widely used on 3D coordinates measuring systems, this paper focuses on some of the principal sources of uncertainties that exist on the implementation of a Laser Scanner based on dynamic triangulation and mainly on its passive element. By analyzing the processed signal on different environmental conditions and the issues by the instability of driving of a brushed DC motor, it is proposed the closed-loop control scheme to reduce these performance issues and further experimentation to demonstrate the results obtained with the proposed method.
