What can you do with a CT?
The cross-sectional images produced of the examined object not only reveal the interior composition of the object, but additionally help identify the presence and cause of defects within the specimen, without altering the test sample. Furthermore, the CT allows the distribution of aggregates within a specimen to be quantified whilst the object is measured internally and externally simultaneously with high accuracy. Due to the short measuring time, it is also possible to investigate dynamic processes and track the internal changes of the object in 3D. Luci has the ability to examine a wide-range of materials: from wood and aluminium, to steel or even denser samples. In particular, biological samples such as, vegetables, fruits, cheese and even biological tissue can be examined.
- Penetration capability: 225 kV source (equivalent to 150 mm solid aluminium or 7 mm solid steel)
- Focal spot size: starting from 0.5 microns
- CT resolution: In principle the resolution is the diameter of the field of view divided by 3000/6000 (with measuring circuit extension), but at most 0.5-1 micrometre
- Radiography resolution: 2800 x 2800 pixels with 15 frames per second (full frame) and up to 85 frames per second with 2 x 2 binning
- Measurement circuit extension: By combining 2 horizontally or vertically shifted measurements, the field of view can be doubled.
- Helix scan: Objects with a length up to 60 cm can be measured in a single experiment
- Permissible sample size: Diameter 520 mm, height 650 mm, 20 kg (precision measurement), 50 kg (standard measurement)
- Suitable for metrology: Due to the solid granite manipulator base and the temperature in the measuring chamber, the system is suitable for metrological tasks
- Distribution analysis: Whether aggregates in concrete, rock in asphalt or nuts and nougat in chocolate, CT supports you in measuring the position and orientation of each component in the sample and their relative distributions.
- Defect analysis: CT offers the possibility to look inside a component without having to disassemble it. Therefore, you have the possibility to perform defect analysis without altering the test object.
- Metrology and shape acquisition: CT allows you to measure exact external and internal geometries and thus determines the shapes of objects without needing invasive or destructive techniques.
- Input data for simulations: Since CT can digitalise the shape of objects, the input geometry data for structural, thermal, or fluid mechanical simulations can be determined directly from the CT measurements. The true geometry of the object can subsequently be used for simulations.
- In-situ measurements: Owing to the large measuring room, loading devices for tension/compression/humidity measurements, heating or cooling tests and moisture loads can be installed. Therefore, measurements of the object under load can be carried out.
- 4D measurements: Thanks to short measuring times or time-lapse recordings, dynamic processes can additionally be investigated. This permits, for example, to track the development of defects within the sample materials in the object and their relative densities.
