Our lab facilities
We provide a variety of solutions for tomography and imaging of samples of different sizes and in different environments. Our two tomographs offer the possibility to rapidly image larger samples, or perform a more in-depth high resolution scan of smaller objects.
The 4D Imaging lab at Lund University is specialised in 3D and 4D imaging of a wide variety of samples. The facilities are located at the Division of Solid Mechanics on the LTH campus premises.
The 4D imaging lab features two X-ray tomographs for studies of samples with sizes ranging from bulk materials to the sub-micron scale. The use of tomography provides a 3D image of the sample, while 4D imaging is achieved through the possibility of studying changes in three spatial dimensions and time simultaneously. Applications of X-ray tomography can be found in several different fields of research, such as energy storage, geomechanics, paper mechanics, and food science.
Our high-resolution 3D X-ray microscope (Zeiss XRM520), allows for pixel sizes down to 700 nanometres and a field of view up to 6 cm. Samples with a diameter up to 300 mm and a weight of 15 kg can be scanned and polycrystalline structures can be studied using diffraction contrast tomography. Our micro X-ray tomograph (RX Solutions EasyTom150) allows for imaging of large samples, with a size up to 35 cm x 45 cm, and a tomography acquisition time of about 10 seconds. Both tomographs are equipped with accompanying software for image reconstruction, visualisation and data quantification.
Different sample environments can be used together with the tomographs to perform in-situ testing during various sample conditions. Examples includes pressure cells, fluid flow, uniaxial compression or tension, and vacuum testing.
