BENTHOWAVE INSTRUMENT INC. Acoustic Transducer & System
BII-7740s are bespoke high power broadband annular array (ring-array) transducers which have radially distributed symmetric ring elements on the circular radiation face. The elements are driven separately with voltage sources to support the amplitude shading (weighting), array focusing and spreading, acoustical imaging (Microscope, Holography, and Tomography), and tune the best compromise between main-beam sharpness and the side-lobe suppression. A dual beam or dual frequency transducer can be implemented by wiring different elements for transmit and receive. Besides, BII-7740s can also be used in passive SONAR (listening sounds).
