Abstract
The invention relates to a system for detecting and locating surface discontinuity by a light beam; it is more particularly intended for detecting any discontinuity forming a line on this surface, or any discontinuity forming two opposite lines on this surface. In the latter case, this discontinuity may, for example, be the join defined by the opposite edges of two metal sheets to be welded.
