What is the Accuracy of Laser Scanning and how does that Differ from Resolution?
The standard laser resolutions offered by Laser Design are 10m and 25m although we have built custom systems with finer laser resolutions. When considering any optically based measuring systems, it is important to realize that there is a difference between the terms resolution and accuracy. Resolution is simply the smallest change in distance that the sensor is capable of detecting, and is proportional to the point spacing along the laser line. Accuracy, on the other hand, describes how closely the measurements of the laser conform to the true dimensions of the object being measured. LDI determines accuracy by measuring the position of a vertex target in multiple positions throughout the laser field of view. The true position of the target is measured using a high accuracy mechanical positioning base. Comparing the laser measurement to the true position value gives you the measurement error for each point. The accuracy of the laser is the total error bandwidth over all measurements wit
