What types of noise are suppressed?
Noise means any unwanted signal. Usually this takes two forms: (1) random spikes (due to motors, welders, cranes, etc.) and, (2) material back scatter (due to grain structure). The NSII can be used to suppress either or both types of noise . However, using the more general definition of noise as any unwanted signal broadens the use of the NSII in your inspection process. For instance, a geometrical reflector such as from weld geometry or the surface wave of a time-of-flight-diffraction setup can also be considered as unwanted signals . The NSII can also be used to suppress these signal types.
