Contrôle RadioSynthétique® applied to composite materials

News International-French

17 Feb 2011

Spectroscan was created in March 2007 on the basis of a new development in 3D X-ray imaging called Contrôle RadioSynthétique®. The young company’s approach to tomography is real-time, industrial and innovative.



Contrôle RadioSynthétique® (CRS®) is an X-ray imaging process that yields numerical sections within the volume of an industrial product in real time for characterization purposes and/or to carry out an instant dimensional inspection. The operator can choose the orientation for the sections.


A cutting-edge innovation

The principle underlying the new process represents a major breakthrough in tomography. Without requiring any specific computing environment, the process pushes the limits of 3D X-ray imaging not only in terms of image quality, but also for acquisition and processing time. Its functional model meets all of the most recent production management standards.


An industrial approach

With respect to the overall production facilities, the approach enables the engineering department to initiate a testing programme as soon as the product is designed, and then each time the product is changed.


CRS® is a collaborative tool that is designed to fit the Product Lifecycle Management (PLM) concept by ensuring:


  • cost reduction from design to production,
  • shorter prototyping and testing times,
  • non-destructive testing along the production line.


Quality requirements


The overall quality conforms to the latest international recommendations on metrological control processes used along the production line. CRS® is a tolerancing-based control/measurement process that complies with the CAT2009 recommendations. The process relies on:


  • metrological control processes that use real-time 3D analysis,
  • inertial tolerancing of batches on the production lines,
  • a method that uses engineering department data to control the geometric variations of the manufacturing process.


CRS® is particularly well suited to the study and characterization of composite materials at different scales: microscopic (≤ 1 μm), mesoscopic (>1μm to 3 mm) or macroscopic (>3 mm up to a number of metres).


Practical examples of studies performed


Samples (approximately 125 mm3) for non-destructive testing of local and overall reinforcement fibre orientation, of areas where segregation and embrittlement have occurred, and of spatial and size distribution for porosities.


This innovative development in industrial imaging provides better resolution and shorter recovery time in 3D imaging. Spectroscan’s patented radiosynthesis technology offers a number of potential applications in the field of inspection and rapid characterization of materials.


For all of its markets, the company also guarantees optimum adaptability of the acquisition processes for maximum quality and quantity of reconstruction data, in part by introducing a robotic tool that is immediately programmable for the target application. In this way, Spectroscan is facilitating non-destructive testing for a broad range of parts and materials.
