Abstract:
1. An inspection system to detect imperfections in materials comprising: at least one imperfection detection sensor with an output, said output comprising imperfection signals in a time-varying electrical form; at least one computer having at least one imperfection detection interface, wherein said output is normalized and decomposed in frequency and is in communication with said at least one computer, and wherein said at least one computer converts the frequency decomposed imperfection signals to a digital format; at least one memory storage for said at least one computer, wherein said output can be stored; and a program, said program being executed on said at least one computer, and said program being configured to operate on said converted frequency decomposed imperfection signals, wherein said operation evaluates and/or manages said converted frequency decomposed imperfection signals, wherein said conversion to digital format further comprises at least one sampling rate, and wherein the at least one sampling rate of said conversion to digital format is at least partially controlled by a scanning speed of the inspection system.
