FIG. 1.

The design of an array transducer consisting of cylindrically focused PVDF detectors and frequency band of a single array element.

FIG. 2.

(a) Numerically calculated OA signal detected by a wideband cylindrically focused transducer from a point source located at its focus. (b) The OA signal processed according to the backprojection algorithm.

FIG. 3.

An example of numerically calculated focal area map of a cylindrically focused wideband transducer. Thick line borders the region.

FIG. 4.

Dependencies of the resolution (a) and the monitoring depth (b) of a cylindrically focused transducer on its aperture angle for different bandwidths. Symbols denote numerically obtained values, lines—the corresponding fit determined by Eqs. (1) and (2).
