Abstract: A device and method for analyzing structures within a medium. The device may include: at least one acoustic signal transmitter and acoustic signal receiver configured to output an acoustic signal and to receive an acoustic signal; an analyzer configured to analyze received acoustic data; a signal modifier configured to modify the acoustic signal of the acoustic signal transmitter or acoustic signal receiver; and control circuitry for controlling analysis of the structure. The control circuitry is configured to: initiate analysis of a first portion of the structure by controlling the signal modifier to apply a signal modification to the transmitter or the receiver to modify respective acoustic signals according to first modification data; and initiate analysis of a second portion of the structure by controlling the signal modifier to apply a signal modification to the transmitter or the receiver to modify respective acoustic signals according to second modification data.

Abstract: A device and method for analyzing structures within a borehole is disclosed. The device comprises: a medium determiner for determining a medium surrounding the device; at least one acoustic signal transmitter and acoustic signal receiver configured to output an acoustic signal and to receive an acoustic signal; and a signal modifier configured to modify at least one of a phase and amplitude of the acoustic signal at at least one of the acoustic signal transmitter and acoustic signal receiver. The signal modifier is configured to receive a medium indicator signal from the medium determiner indicative of the medium surrounding the device and to apply a signal modification to at least one of the at least one acoustic signal transmitter and acoustic signal receiver in dependence upon the medium indicator signal.
