Infrared thermography (IRT) is an emerging non-destructive examination (NDE) method with considerable capability to detect reinforcement in concrete structures. This research employs Thermographic Signal Reconstruction (TSR) and phase imaging methodologies to facilitate precise identification of reinforcement. TSR reconstructs transient thermal signals, diminishing noise and reducing the effects of surface emissivity fluctuations, whereas phase imaging examines thermal wave phase shifts, facilitating accurate detection of reinforcement, even at substantial depths. IRT offers considerable benefits compared to conventional techniques like ground-penetrating radar (GPR) and radiography. In contrast to GPR, which is susceptible to moisture and material variability, IRT consistently offers reliable performance across diverse situations. Moreover, it circumvents the safety risks and logistical complexities linked to radiography, providing a completely contactless, quick, and effective method for examining extensive areas. The research illustrates that TSR and phase imaging can consistently identify reinforcement implanted at a depth of 20 mm from the surface, yielding distinct thermal contrasts and precise localization. The findings of this study contribute to the advancement of non-invasive structural health monitoring in civil engineering by establishing IRT as a practical and cost-effective tool for reinforcement detection.
