About

Bernd Fischer is a leading figure in terahertz (THz) imaging and spectroscopy, with a particular focus on developing practical systems for non-destructive evaluation. His most-cited work, "A THz Tomography System for Arbitrarily Shaped Samples" (2017, 36 citations), represents a significant breakthrough in the field. This paper introduced a novel approach to THz computed tomography that overcomes a major limitation of earlier systems: the inability to image objects with complex, non-cylindrical geometries. By implementing a flexible scanning mechanism and tailored reconstruction algorithms, Fischer enabled high-resolution, three-dimensional imaging of arbitrarily shaped samples, opening new possibilities for industrial quality control and security screening. This contribution has been widely recognized as a foundational step toward making THz tomography a versatile, real-world tool. Fischer’s research consistently bridges the gap between fundamental physics and applied engineering, and his work continues to influence the design of next-generation THz systems for material characterization and biomedical diagnostics.
