Tomographic analysis method

Abstract

A method for tomographic analysis of a composite part (20) comprising fibers (21), the method comprising the following steps: - acquisition (ACQ) of at least one tomographic image of the part (20) using a tomography device (1), - division (DIV) of the tomographic image into elementary sub-parts, - measurement (MES) of the variations of at least one first quantity (G), characteristic of the gray levels on the sub-part, - obtaining (OBT) the variations of a comparison quantity (C) in at least one reference part, and - comparison (COMP) of the variations of the first quantity (G) with the variations of the comparison quantity (C). The method includes a step of: - registration (REC) of the comparison quantity (C) to compensate for a shift (u) between the first quantity (G) and the comparison quantity (C).
