Encoded Eddy Current Array (ECA) Subsurface Inspection¶
A 32-element Eddy Current Array probe operating at 18 kHz (2 mm pitch) for subsurface defect detection. A temporal low-pass filter at 150 Hz is applied to each channel before spatial sampling to generate the C-scan. The C-scan covers 500 mm in the scanning direction (1 mm resolution) by 62 mm in the array direction (2 mm resolution). An encoder controls spatial sampling along the scanning direction.
