Reduction of the Influence of Laser Beam Directional Dithering in a Laser Triangulation Displacement Probe [PDF]
Sensors, 2017 Directional dithering of a laser beam potentially limits the detection accuracy of a laser triangulation displacement probe. A theoretical analysis indicates that the measurement accuracy will linearly decrease as the laser dithering angle increases.
