Abstract

APARATO PARA LA MEDICION REMOTA DE UN VOLUMEN FISICO, POR MEDIO DE UN SENSOR (20) QUE RECIBE UN FLUJO LUMINOSO TRANSMITIDO ALTERNATIVAMENTE POR DOS FUENTES DE LUZ (10, 12), Y QUE CONSIGUE UNA MODULACION ESPECTRAL DEL FLUJO LUMINOSO RECIBIDO A UNA FRECUENCIA QUE CORRESPONDE A UN VOLUMEN FISICO X QUE SE QUIERA MEDIR, EN EL CUAL EL FLUJO LUMINOSO TRANSMITIDO POR EL SENSOR ES RECIBIDO POR MEDIOS ANALIZADORES (24) QUE CONTIENEN CUBOS DE SEPARACION DE POLARIZACION (28, 40, 42) UNIDOS A CELULAS FOTOSENSITIVAS (50), Y A MEDIOS DE PROCESAMIENTO DE INFORMACION, PARA DETERMINAR LA FASE ABSOLUTA DE LA SEÑAL LUMINOSA RECIBIDA Y DEDUCIR DE LA MISMA EL VALOR DEL VOLUMEN X QUE SE VA A MEDIR. ESTA INVENCION PROPORCIONA UNAS MEDICIONES MUY EXACTAS DE VOLUMENES FISICOS A DISTANCIA.
