Abstract
Electronic scanning of a mosaic transducer array enables underwater sound pressure patterns to be reproduced on a cathode ray tube using intensity modulation. This report presents the design of a 16 element electronically scanned linear array mounted directly to the edge of a 10 cm by 15 cm printed circuit board. Microelectronic devices are used to confine all electronics to a 6 mm by 6mm cross section behind each array element. A large number of identical circuit boards such as this could be stacked to form a two-dimensional array suitable for acoustic image conversion or acoustical holography. A discussion of experimental results, size, and cost is given.
