Claim 5:
6. A system comprising:
an optical fiber disposed in a wellbore and arranged such that the optical fiber is operatively subjected to seismic waves;
an optical source arranged to operatively couple an optical signal into the optical fiber;
an interrogator having an optical receiver arranged to operatively receive optical responses from the optical fiber in response to backscattered optical signal from the optical fiber;
a processor arranged to:
process optical responses acquired from interrogation of the optical fiber, the processing to provide a first seismic wavefield with a first gauge length applied; and
convert the first seismic wavefield to a seismic wavefield with a different gauge length, the different gauge length being a positive integer multiple of the first gauge length.
