Abstract

SE PRESENTA UN APARATO PARA LA MEDIDA DE LA VELOCIDAD DE UN FLUIDO QUE UTILIZA UN ANALISIS ESPECTRAL DE DESPLAZAMIENTO DOPPLER QUE INCLUYE UNA FUENTE DE LUZ DE ANCHO DE LINEA ESTRECHA (1), CUYA LUZ PASA A TRAVES DE UN EXPANSOR DE RAYO (3) PARA SUMINISTRAR UNA REGION IRRADIADA, POR EJEMPLO UN PLANO BIDIMENSIONAL, EN LA CUAL PUEDE OBTENERSE UNA MEDIDA DE LA VELOCIDAD. LA LUZ EMITIDA POR PARTICULAS PEQUEÑAS EN LA REGION IRRADIADA EN RECOGIDA EN UN SISTEMA DE FORMACION DE IMAGENES (4) QUE HACE POSIBLE EL ANALISIS ESPECTRAL DE LA LUZ DISPERSADA PARA DETERMINAR LA VELOCIDAD DE LAS PARTICULAS EMISORAS DE LUZ EN LA REGION IRRADIADA. SE UTILIZA UNA CAMARA SIMPLE (13) EN EL SISTEMA DE FORMACION DE IMAGENES (4) PARA EVITAR LA NECESIDAD DE DISPOSITIVOS ELECTRONICOS COSTOSOS PARA SINCRONIZAR LAS IMAGENES OBTENIDAS. TAMBIEN PARA MEJORAR LA EXACTITUD DE LA MEDIDA, PUEDEN MEDIRSE PARAMETROS SELECCIONADOS DEL APARATO (2, 5) PARA PERMITIR PERTURBACIONES EN LAS MEDIDAS DE VELOCIDAD OBTENIDAS.
