Abstract

Una estación de detección fotoeléctrica, que incluye un circuito para operar varias estaciones de detección fotoeléctricas cada una de las cuales comprende un diodo semiconductor operado por impulsos como transmisor un fototransistor como receptor, y un circuito de evaluación, caracterizado porque un contador (3) cuya capacidad corresponde al número de diodos semiconductores (6) y que se hace avanzar por los impulsos, conecta los diosos (6) uno detrás de otro, porque los fototransistores (8) están conectados en paralelo y seguidos por un único circuito de evaluación (13) porque existen memorias (14) que son en número igual al de los fototransistores (8) y cuyas entradas están conectadas en paralelo y a la salida del circuito de evaluación (13), y porque las memorias (14) se conectan simultáneamente con los diodos (6).
