Abstract
This system for measuring the propagation of a zone of separation between a first portion and a second portion of at least one substrate includes: a module for emitting at least two incident beams each of which illuminates a separate point on the substrate, the at least two incident beams being able to pass through the first portion and the zone of separation and meet the second portion in such a way that each of them generates at least one first emergent beam Fe originating from the interface between the first portion and the zone of separation, and at least one second emergent beam originating from the interface between the zone of separation and the second portion; a detecting module for detecting light intensity values resulting from interference between the first and second emergent beams; and a computer for determining the conditions of the propagation of the zone of separation.
