  • Abstract
    A focusing p.v.f.2 transducer is described. By controlled deformation of a stretched p.v.f.2 membrane, the focal spot may be scanned axially. This action is demonstrated and is shown to correspond well with the predictions of simple theory. There are potential applications for such a device in medical imaging.
