N2 - This paper describes a linear 1-D solid-state-based magneto-inductive sensor array for detecting and imaging steel-reinforcing bars embedded within prestressed and reinforced concrete. Using a square coil of 300 mm × 300 mm × 2.5 mm and by only measures of the vertical component of the magnetic flux density, pictorial representation of embedded rebars of different diameters and configurations can be imaged down up to a depth of 100 mm. The system is also capable of imaging metallic objects of different shapes. Experimental results obtained by scanning different steel bar specimens are presented.
