O que é Non-Destructive Testing using Remote Sensing?

Non-Destructive Testing (NDT) using Remote Sensing is a technique that allows the evaluation of materials and structures without causing any damage. It involves the use of various remote sensing technologies to gather data and analyze the condition of objects or systems. This approach is widely used in the field of engineering to assess the integrity and performance of critical components, ensuring their safety and reliability.

Princípios

O NDT using Remote Sensing is based on the principles of utilizing non-invasive methods to obtain information about the internal and external characteristics of a material or structure. It relies on the interaction between the object being tested and the remote sensing technology employed, such as electromagnetic radiation or acoustic waves. By analyzing the data collected, engineers can identify defects, anomalies, or changes in the material’s properties without causing any harm.
