Presence of Visual Interferences
Presence of strong electromagnetic interference could generate noise in the signal that
is visually detectable. This interference is temporary and random in comparison with
the signals generated by the physical features of the inspected part, which are
coherent and persistent. This interference depends greatly on the nature, strength,
and proximity of the electromagnetic source and it will only disappear when the
source of the noise is no longer emitting signals.
