Abstract

EL AVISADOR DE HUMOS CONTIENE UNA FUENTE LUMINOSA (1), UN TRAMO DE MEDICION (3) IMPULSADO POR LA FUENTE LUMINOSA (1) Y QUE MUESTRA UN RECEPTOR DE MEDICION (5), UN TRAMO REFERENCIAL (2) IMPULSADO POR LA FUENTE LUMINOSA (1) Y QUE MUESTRA UN RECEPTOR REFERENCIAL (4), Y UN CIRCUITO DE VALORACION (6) CONECTADO A LOS CITADOS RECEPTORES (4, 5). EL RECEPTOR DE MEDICION (5) Y EL RECEPTOR REFERENCIAL (4) SE HAN CONFORMADO CON LA MISMA ESTRUCTURA Y RECIBEN LA MISMA CANTIDAD DE RADIACION DE LA FUENTE LUMINOSA (1). A PARTIR DE LA SEÑAL DE CORRIENTE (I R ) DEL RECEPTOR REFERENCIAL (4) Y DE LA SEÑAL DE CORRIENTE (I M ) DEL RECEPTOR DE MEDICION (5) SE FORMA UNA SEÑAL DIFERENCIAL ( DL L) Y SE ALIMENTA AL CIRCUITO DE VALORACION. A LA SEÑAL DE CORRIENTE (I R ) DEL RECEPTOR REFERENCIAL (4) SE SUPERPONE UNA CORRIENTE REFERENCIAL (I K ) Y LA FUENTE LUMINOSA SE CONECTA A UN CIRCUITO REGULADOR Y SE REGULA MEDIANTE EL MISMO, DE TAL MANERA QUE SE PRODUCE UNA COMPENSACION COMPLETA DE LA CORRIENTE REFERENCIAL (I K ) MEDIANTE LA FOTOCORRIENTE (I S UB,R ) DEL RECEPTOR REFERENCIAL (4). A LA SEÑAL DIFERENCIAL ( DL L) SE SUPERPONE UNA SEÑAL DE COMPENSACION (I K ), A TR AVES DE LA CUAL SE PRODUCE UNA COMPENSACION A CERO DE LA MISMA.
