Abstract
APARATO Y METODO PARA MEDIR LA PRESION PARCIAL DE OXIGENO EN UN FLUIDO. UN SENSOR FOSFORESCENTE SE SOMETE A UN FLUIDO QUE CONTIENE OXIGENO. UA FUENTE LUMINOSA MODULADA CON UNA ONDA SINUSOIDAL EXCITA AL SENSOR, PARA PRODUCIR CON ELLO UNA LUZ EMITIDA QUE TIENE UNA ONDA SINUSOIDAL. SE COMPARA EL CAMBIO DE FASE ENTRE LAS FUENTES LUMINOSAS DE EXCITACION Y EMISION, SIENDO EL CAMBIO DE FASE UNA MEDIDA DE LA PRESION DEL OXIGENO.
