Abstract
An apparatus for acoustic imaging includes an array with a number of acoustic transducers. Each acoustic transducer transmits and receives acoustic signals. The apparatus also includes a control unit that is coupled to the array and selectively powers a number of acoustic transducers based upon standoff distance between the array and an object-of-interest (e.g., a borehole wall). In some embodiments, the control unit also varies the frequency of acoustic signals transmitted from the array using the standoff distance between the array and the object-of-interest.
