Automatic inspection of pipelines using tomographic imaging technique

Electromagnetic (EM) inspection techniques are widely used in a broad range of applications. Everyday examples include metal detector for security screening to vehicle detectors at traffic lights, however there are also numerous applications throughout industry (e.g. non-destructive testing, material inspection, security screening, foreign body detection, etc.).The aim of our project is to develop the sensor array, and test it for inspection of metallic pipelines, especially those of under cladding. The geometrical information in pipeline application is different than the traditional EMT system. Here, we will only be interested in imaging the pipeline area (which is a concentric circle). The cladding (in particular if it is made of non-conductor or thin layer conductor) material will not have an impact in our observations and the oil/gas that are running inside the pipe will have no or very little impact on our signals. That means that the inspection can be done without removing cladding and without requirement to stop the fluid running.
