XTIA’s technology is based on optical frequency combs, coaxial laser systems that scan objects and give access to the full 3D profile of parts with high accuracy. With this Nobel-winning technology, Optocomb 3D scanners by XTIA are capable of measuring 500,000 data points per second, a high-speed performance that significantly shortens the time to scan manufactured parts. As a result, they are the ideal solution for a fully automated dimensional inspection of complex structures such as cast, forged, and machined parts. Breaking up with existing technologies, Optocomb 3D scanners by XTIA thus represent a major breakthrough in the field of inspection.

XTIA sensors can determine the 3D dimensions of defects on casting, forging, and machined parts.
Engineering is a world where quantitative judgment should and can be made, but this has often been difficult to achieve on a manufacturing floor dominated by human inspection. However, with the automated inspection solutions offered by XTIA, quantitative inspection and engineering of micrometer defects is finally possible: Optocomb 3D scanners by XTIA have a reliable track record for the detection of a large range of 3D defects such as dents, scratches, particles, burrs and more. Scratches of different depths can for example be detected, and their dimensions measured at the micrometer level. With a quantitative information on three-dimensional defects, quality assessment becomes more reliable and manufacturers can build a more rational production system.
Beyond scratches, Optocomb 3D scanners by XTIA can detect a range of micro-defects including burrs. Burrs are a constant battle for machined parts. They are notoriously difficult to eliminate due to the nature of the manufacturing process. And yet, they often lead to significant dysfunction during the assembly process or the final product operation. Because burrs are typically small, their detection is difficult, and how to keep them from being passed on to the next process remains a complex manufacturing issue. With the optical comb technology, however, a long working distance combined with a coaxial configuration makes it possible to easily inspect burrs within complex structures at the micrometer level.

- Cylinder block
- Brake and solenoid valves
- ✓Inner walls inspection
- ✓Diameter inspection
Many medium and large parts have a cylindrical features that need to meet high quality requirements and the ever-demanding designs of modern manufacturing. XTIA has thus developed its Helical Scan. It combines XTIA's high-accuracy Optocomb sensor with a rotating mirror that translates within the structure along its rotating axis to probe the inner walls of bores. With this system, XTIA brings a new visual and dimensional inspection solution to the table and enables the inner surface of bores and other cylindrical structures to be measured with high accuracy. This solution gives direct access to the position, diameter, cylindricity, circularity and depth of your bores with diameters ranging from 20 mm to 60 mm.
Helical Scan by XTIA thus covers a large range of manufactured parts such as cylinder blocks, brake valves, solenoid valves, conrods, bearings and more. Moreover, it can detect and extract the dimensions of various 3D micro-defects such as foreign particles, burrs, scratches that one can find on the inner walls of bores.
Detecting process variations with high-accuracy to enable its correction.
Automatic volume calculation of combustion chambers with high accuracy.
The optical comb technology and XTIA’s coaxial laser scanners provide access to the dimensional profile of complex structures with high accuracy. As a result, XTIA’s solutions can be extremely valuable if integrated within the manufacturing process flow, because it opens the door to the reduction of geometric tolerances by a specific correction process. Geometric tolerance is defined as the amount of variation that can be tolerated, taking into account the capabilities of the manufacturing process. Nowadays, the quest for higher performance and aggressive designs in all manufactured products has led to one of the biggest challenges in product design and manufacturing: how to reduce this variation. With a fully automated inspection of all manufactured parts, the inspection data can be used to implement a correction process and significantly minimize this variation.
More specifically, with its L90 wide-range sensor, XTIA has a proven track record in the correction of cylinder heads, an automotive component that controls fuel efficiency. In a combustion engine, the piston moves up and down inside the cylinder, and the volume generated by the upper and lower limit of this movement defines the displacement volume. As you increase the compression ratio, your car's fuel efficiency will improve. However, beyond a given limit, increasing the compression ratio leads to abnormal combustion and a knocking phenomenon is likely to occur. The key to improving fuel efficiency is thus to raise the compression ratio to a level that will prevent such abnormal combustion and subsequent reliability problems. To avoid such reliability problems while accounting for variations from cylinder to cylinder, it is thus necessary to design a safe compression ratio. Of course, with this conservative design the engine is functioning but with a suboptimal performance. To implement more aggressive designs and optimize the engine performance it is thus necessary to know the exact volume of the manufactured chamber and leverage this information to subsequently reduce the deviation through a correction process.
Optocomb 3D scanners by XTIA have the unique ability to measure the full profile of such combustion chambers and extract their volume with high accuracy. In turn, this high measurement accuracy can be passed on to the correction process and XTIA has demonstrated that volumetric variation can be reduced down to a standard deviation of less than 0.01 cc.
