    Hello experts,
    I’m wondering which techniques are used to make a map of an area, in order to locate flaws on the surface.
    I read that it is doable with a sheet with plenty of pancake coil (10 to 100), but it seems complicated to connect and operate all these.
    Have you got better solutions to avoid the previous one ?
    What are the advantages and inconvenience ?
    Thanks for helping
    products austenitic stainless steel and similar alloys. it may help you.

    you would need to use some sort of multiplexer to drive your pancake coils, otherwise there will be much cross-talk between the coils and it will affect data quality.

    What are you using to drive your coils?
