Filip Lajčiak, a student at the Secondary Technical School in Dubnica nad Váhom, has secured first place in his category at the 2026 Regeneron International Science and Engineering Fair (ISEF) in the United States. The high schooler was recognized for developing an innovative stereovision 3D scanning system designed to capture microscopic samples.
Innovation in Microscopic Imaging
The project developed by Lajčiak integrates several complex fields, including microscopy, electronics, a camera system, mechanical positioning, and software-based image processing. According to Ján Nemec of the Association for Youth, Science and Technology (AMAVET), the system utilizes a pair of images captured from slightly different angles.
By analyzing these images, the system can calculate the spatial structure of a sample and generate a digital 3D model. This approach provides a more accessible alternative to professional 3D imaging systems, which are typically characterized by high financial and technical requirements.
Academic Pathway and Mentorship
Lajčiak’s journey to the global competition began with the title of “scientific talent SAV,” awarded by the Slovak Academy of Sciences at the 2025 AMAVET Festival of Science and Technology (FVAT). He subsequently advanced to the United States as a national winner of the FVAT AMAVET.
The project was developed under the professional guidance of Ján Vachálek from the Slovak University of Technology in Bratislava. Vachálek assisted the student in aligning the project’s technical direction, bridging theoretical knowledge with practical development, and preparing the presentation for the international jury.
Future Potential and Implications
Ján Vachálek noted that the professional level of projects winning at prestigious competitions like Regeneron ISEF is exceptionally high. He stated that such work often approaches the level of a doctoral thesis.
Because of this depth, these projects could naturally evolve into professional publications or patent solutions. There is a possibility that this specific research may lead to further study with real innovation potential in the field of microscopic imaging.
