Abstract

UN FLUJOMETRO DE SANGRE RETINAL (10) PROYECTA UN HAZ DE ILUMINACION A TRAVES DE UN SISTEMA DE CONTROL (20) SOBRE UN VASO RETINAL, Y FORMA UNA IMAGEN SEGUIDORA SEPARADA DETRAS DEL SISTEMA DE CONTROL. UN BUCLE SEGUIDOR RAPIDO DETECTA EL MOVIMIENTO DE LA IMAGEN SEGUIDORA Y MUEVE EL SISTEMA DE CONTROL CON UN MOVIMIENTO DE IMAGEN NULA Y MANTIENE EL HAZ DE ILUMINACION CENTRADO SOBRE EL VASO. EL HAZ SE REFLEJA DESDE EL VASO, RECOGIDO POR DETECTORES (49) EN DOS ANGULOS FIJOS, Y ES PROCESADO POR ANALISIS ESPECTRAL. EN UNA CONFIGURACION PREFERIDA, EL HAZ DE ILUMINACION Y LA IMAGEN SEGUIDORA SIGUEN CAMINOS TOTALMENTE SEPARADOS A TRAVES DEL SISTEMA DE CONTROL. FIBRAS OPTICAS (47) TRASLADAN LA LUZ DOPPLER RECOGIDA SIN DISPERSION MIENTRAS PRESERVAN LAS RELACIONES DE FASE Y LAS DIMENSIONES ABSOLUTAS SON DETERMINADAS POR LA ELECTRONICA DE SEGUIMIENTO DE LA IMAGEN. UN PROCESADOR (116) CALCULA A CONTINUACION EL FLUJO VOLUMETRICO DE SANGRE, COMPARANDOLO CON LOS VALORES NORMALES.
