Abstract
Coincidence measurement system of concentricity and horizontality is proposed in this paper. The measurement system can be used in the assembly of large structures, such as aircrafts, because it can quantitatively display the concentricity and horizontality in real time without any contact between the system and the structure by using a laser system. The system consists of only optical components on one side of the measurement system, i.e., the target. The other side of the measurement system consists of optical and electrical components. Therefore, the measurement system can be used in the assembly of anti-electrical shock structures. The standard deviation of concentricity and horizontality were 31.85µm and 0.001036° at a distance of 0.985m, respectively. The quantitatively measured data could be indicated at 3frames/s of displayed speed.
