Abstract
In optoelectronic scanning, it has been found that in order to find the position of a light source, the signal obtained looks like a Gaussian signal shape. This is mainly observed when the light source searched by the optoelectronic scanning is punctual, due to the fact that when the punctual light source expands its radius a cone-like or an even more complex shape is formed depending on the properties of the medium through which the light is trav‐ elling. To reduce errors in position measurements, the best solution is taking the measure‐ ment in the energy centre of the signal generated by the scanner, see [1]. The Energy Centre of the signal concept considers the points listed below, see [2], in order to search which one of them represents the most precise measurement results:
