Abstract

Sistema acústico de formación de imagen para presentar un objeto observado, caracterizado porque incluye un conjunto dispuesto lateralmente de una pluralidad de transductores acústicos respectivamente separados por una distancia conocida con relación a un punto dado y orientados para transmitir y recibir señales acústicas a lo largo de trayectos de transmisión preestablecidos sustancialmente paralelos a un plano predeterminado, unos medios para hacer pivotar el conjunto dentro del plano predeterminado alrededor del punto dado, unos medios para activar los transductores del conjunto para transmitir y recibir las señales acústicas, unos medios para generar tensiones de salida para cada recepción respectiva de una señal acústica, correspondiendo a la posición de coordenadas del objeto observado cuando se hace pivotar el conjunto y unos medios para presentar la recepción de cada transductor en la misma pantalla de visualización que su posición de coordenadas correspondiente.
