Tomsk Open Laboratory for Material inspection (TOLMI) was established in 2010 within the scope of the Ministry of Russian Education and Science program that was aimed to attract and recruit leading international scientists. The laboratory was founded on the basis of the School of Non-Destructive Testing & Security. Hans-Michael Kroening, the former director of Fraunhofer Institute of Nondestructive testing of the University of Saarland, became the leading scientist of TOLMI.

The laboratory main goal is the development of advanced products of nondestructive testing, providing national and international excellence in this and related areas.

The laboratory team consists of young scientists pursuing innovative research ideas and professionals with solid fundamental research background allowing put forward new original solutions.

In addition, close cooperation of TOLMI with international research institutions allows creating technologies that meet the world standards of non-destructive testing and helps to increase international technology transfer.

The main field of research includes the implementation of various non-destructive methods such as ultrasonic testing, X-ray, and optical scanning.

TOLMI has a broad research experience in the study of a wide range of materials. The laboratory provides accurate assessment of the quality of different types of metals, such as steel and aluminum, ceramics, and composite structures.

One of the main strong suits of the laboratory is its collaboration with the industrial sector. 

Non-destructive testing is considered to be the most important aspect, ensuring effective manufacturing in various industries, especially for the most safety-critical ones, such as military, aerospace, and energy. Therefore, all solutions developed by the laboratory represent the implementation of advanced scientific methods in accordance with the needs of the manufacturing processes of these industries.

For that reason, TOLMI offers the innovative approach for quality assessment, based on the application of tomography for industrial control.

As one of these solutions, the laboratory developed a specialized ultrasound tomography system. The system hardware includes several innovative aspects in the field of measuring technology, microelectronics, compact parallel computing systems, and high-speed processing of large data sets.

TOLMI in collaboration with Fraunhofer Institute for Nondestructive Testing developed its own algorithms for reconstruction of acoustic signal (Digitally Focused Array Technique, DFA), allowing to obtain 3D images of the structure of a controlled object with high resolution in real time. The results of the control can be presented as A, B, C - scans, and in the form of a 3-D visualization of the inner structure of the controlled object for the purpose of accurate quality assessment.

This ultrasound tomography system is a combination of advanced acoustic testing methods, visualization and reconstruction techniques, and modern robotic systems.


The implementation of robotic systems corresponds to another series of solutions that are offered by TOLMI in order to increase safety and industrial efficiency.

Such as the implementation of robotic instruments for the purposes of optical scanning.

The developed solutions are based on the application of structured light technique with the use of triangulation range scanners, which exploit emission of a controlled light pattern toward the scanned object. For that purpose, the TOLMI research team a special software was developed that allows reconstructing the shape and the surface of an object. In addition to the robotic manipulator, it enables to reconstruct 3D models of objects with complex geometry and any arbitrary dimensions.

Along with these, the laboratory has experience in development of robotic X-ray high-energy tomographs, able significantly increase quality and reduce scanning time of the inner structures of an object.

In this regard, the proposed X-ray testing method was based on a non-standard geometry of tomographic scanning and development of specialized back-projection algorithm using a fan-shaped beam. It enables to apply 3D tomographic analysis for quality evaluation of complex objects even when the size of the component exceeds dimensions of the equipment.

TOLMI has a wide R&D experience, including different contract-based projects and grants under the scope of the Ministry of Education and Science of the Russian Federation programs such as the Federal Target Programme - R&D for priority areas of the development of S&T complex of Russia 2014 — 2020, and Federal Assignments: Science.
