Underwater Acoustic Transducers
One of APS’s specialties is the design, fabrication and use of directional and “vector” transducers – the latter of which might be considered a multidimensional extension of the former.  Our vector transducer designs fall into three general classes: diffraction-type gradient sensors; multi-mode gradient sensors; and inertial (i.e., particle) motion vector sensors.  Each has particular advantages depending on the application.

APS/Acoustech have designed and built.
