TYPE OF DATA: 2D eddy-current scan data (@ single frequency)

DATES OF ACQUISITION: 21st May 2015 - 7th July 2015

DATA ACQUIRED BY: Robert R. Hughes

CONTACT PERSON: Dr Robert R. Hughes, University of Bristol, e-mail: [e-mail]

JOURNAL PUBLISHING THE DATA: NDT&E International

TOTAL NUMBER OF FOLDERS: 03

TOTAL NUMBER OF FILES: 1 (.xlsx) and 03 x 36 (.mat)

-------------------------------------------------------------------------------------------------------------

DESCRIPTION OF THE DATA ACQUISITION:

The complex scan data was acquired using a 1.14mm outer diameter, ferrite cored and sheilded solenoid coil of 35 turns manufactured in-house. The data was aquired via in-house Labview software, and the data processed via Python and Matlab.

Each folder contains 36 .mat (Matlab) format files holding the complex data matrix for each scan. The following additional information may be useful for interpreting the data:

scan pitch: x = 0.25 mm, y = 0.25 mm
Frequency: 3.25 MHz and 4 MHz

This folder also contains an .xlsx spreadsheet summarising the peak defect signals, maximum background signal and rms background level.
