ABSTRACT:
A system is provided for optimizing the output power of an acoustic wavetrain emitted from a transducer rotatably mounted in a downhole borehole televiewer for scanning the sidewall of the borehole. The purpose is to prevent destructive interference between the caudal portion of the outgoing wave train and the returning echo signals from the borehole sidewall.
