Modulated opto-acoustic converter

摘要

An opto-acoustic subsystem is provided. The subsystem includes an optical transmitter and an actuator device. The optical transmitter can be positioned at a surface of a wellbore. The actuator device can be positioned in the wellbore and can respond to a modulated electrical signal generated from a modulated optical signal received from the optical transmitter by outputting a modulated acoustical signal into an environment of the wellbore.
