Abstract in another language
Laser triangulation is widely used for displacement measurements. As an optical measurement technology, it offers several benefits over classical mechanical approaches: No force is applied to the target surface that could influence the target, and since no mass has to be moved, a highly dynamic behavior can be achieved. Comparing with other optical measurement systems, triangulation provides a higher resolution (yet, typically over a smaller range) than time-of-flight based systems and is simpler (however, less precise) than interferometric systems. The principal idea behind this method is fairly simple: A laser source is used to project a single spot – there are other sensors available which use lines or even 2-dimensional patterns, but those are not subject of this work – on the target surface. This spot is observed with a detector, usually a single column of photodetectors combined with some optical lenses. The distance of the target surface is then calculated from the angle, under which the laser spot is observed, combined with the known distance and relative orientation between laser source and the detector, using simple trigonometric relations.
