Theory and experiments of super‐resolution focusing using a time‐reversal sink have been investigated in high‐frequency regime [Rosny and Fink, Phys. Rev. Lett. 89] and in audible range [Bavu, Besnainou, Gibiat, Rosny and Fink, Act. Acoust., 93]. This technique, generalized to the case acoustic and vibrational imaging of active sources, allows super‐resolution imaging and provides a new method of characterization of active sources in a known background medium. This imaging technique involves a… CONTINUE READING
