Abstract

EN EL RECEPTOR SUPERPUESTO OPTICO, UNA PARTE DE LA SEÑAL ELECTRICA PRODUCIDA POR TRANSFORMACION OPTICA/ELECTRICA SE DESACOPLA Y PASA A UN DISPOSITIVO REGULADOR (4,5,7,HASTA 10,12 A19). EL DISPOSITIVO REGULADOR DISPONE DE MIEMBROS DE POLARIZACION (4,5), QUE REGULAN LA POLARIZACION DEL RAYO DE LUZ EMITIDO PARA OBTENER LA MAXIMA SEÑAL DE SALIDA ELECTRICA POSIBLE.
