About
Lewis Johnson is a leading figure in nondestructive evaluation (NDE), with a particular focus on the inspection of nonmetallic pipelines. His research centers on the development of advanced microwave and millimeter-wave reflectometry techniques—a form of continuous-wave surface-penetrating radar—for detecting structural flaws in materials that are invisible to conventional methods. Johnson’s most impactful work, with 56 citations, demonstrates the integration of a K-band microwave reflectometry instrument onto an in-line inspection robot, enabling real-time, internal scanning of nonmetallic pipes. This breakthrough addresses a critical gap in infrastructure monitoring, as traditional electromagnetic techniques fail on non-conductive materials. By combining robotics with high-frequency sensing, Johnson has pioneered a practical, automated solution for assessing the integrity of aging water, gas, and chemical pipelines. His contributions are vital for preventing catastrophic failures and extending the lifespan of essential infrastructure. Johnson’s work is widely recognized for its innovation in merging robotics and NDE, and he continues to push the boundaries of in-situ, non-destructive material assessment.
