This paper describes the application of the capacitive imaging (CI) technique to the detection of surface features on conducting specimens. The fundamental theory of the CI technique was briefly described. Comparison was made between the CI technique…
As a new Non-destructive Evaluation (NDE) technique, capacitive imaging (CI) has been used to detect defects in oil pipelines, composite sucker rods and storage tanks in recent years. When a CI sensor is used to detect corrosion defect on a…
