Phased Array Transducer

    

BII7630 Series Phased Array Transducer: Beamforming, Dynamic Focusing.

Beamforming and Total Focusing Method (TFM): Phased array transducers are rectangular (linear) array with custom-fit along-length beamwidth and cross-length beamwidth for uses in oceanography such as location, tracking and search of underwater sound sources in hundreds or thousands meter range, and in acoustical imaging and diagnosis in millimeter range such as biomedical study, NDT & AE, and material study. With dynamic focusing (Total Focusing Method TFM), both resolution and sensitivity are improved in detecting flaws or defects and acoustic imaging. Along-length beam can be steered and focused in ±75° range with array beamforming technology. Multiple beams at different directions can also be formed simultaneously with digital beamforming technology. The side lobes along length can be suppressed with amplitude shading or weighting. Two or four array hydrophones can be used to set up "T" type cross array functioning as Target Angle Estimation System with Mills Cross technique. High resolution image can be formed with the technology of Synthetic Aperture Sequential Imaging. A phased line array transducer (projector) and a phased array hydrophone can work as a multibeam SONAR with Mills Cross technique. Multiple transducers can be wired in parallel electrically to set up a longer line array for reducing along-length beam width in low frequency range.
