Abstract

DISPOSITIVO PARA FORMAR UNA IMAGEN DE UN OBJETO POR MEDIO DE HACES ULTRASONICOS. CONSTA DE UN GRUPO (1) DE TRANSDUCTORES ELECTROACUSTICOS; DE UNA UNIDAD DE RETARDO (17) DISPUESTA PARA RETARDAR LA SEÑAL ELECTRICA GENERADA POR CADA TRANSDUCTOR DEL GRUPO, EN UN PERIODO DE TIEMPO PREDETERMINADO, Y PARA SUMAR LAS SEÑALES RETARDADAS A FIN DE FORMAR UNA SEÑAL RESULTANTE QUE SEA UNA REPRESENTACION ELECTRICA DE LAS SEÑALES ACUSTICAS QUE SE ORIGINAN DESDE UNA DISTANCIA SELECCIONADA O DESDE UNA DIRECCION SELECCIONADA; Y DE MEDIOS PARA CONECTAR UN GRUPO (1) SELECCIONADO DE TRANSDUCTORES A LA UNIDAD DE RETARDO (17). DICHA UNIDAD DE RETARDO (17) ESTA FORMADA POR UNA LINEA DE RETARDO PROVISTA DE TOMAS (19), LAS CUALES FUNCIONAN COMO ENTRADAS (21) PARA LAS SEÑALES QUE SE ORIGINAN DESDE LOS DIVERSOS TRANSDUCTORES, Y CUYA SALIDA (23) ESTA CONECTADA A UN DISPOSITIVO (25) DE TRATAMIENTO DE DICHAS SEÑALES.
