Abstract
An improved electronically focused imaging system for focusing transmitted acoustic waves into a focal line and for scanning the focal line for waves either reflected or transmitted from an object of interest. The system includes N transducer elements in a transmitter array and N transducer elements in a receiver array. These 2N elements can resolve N.sup.2 locations on the object of interest. In one embodiment the transmitter array is pulsed through a delay line that is activated by two, independent, frequency varying chirp signals. In this embodiment the receiver array is focused to scan the focal line and to develop a rectangular raster so that the output of the system is viewable on an oscilloscope or a television screen. In another embodiment the transmitter array is pulsed by a delay line activated by one chirp signal and a 45.degree. raster is developed.
