Abstract
UN DETECTOR OPTICO DE DEFORMACIONES DE EXCITACION PROPIA (20) QUE INCLUYE DOBLES PUENTES PARALELOS (22, 24) QUE TIENEN UNAS SUPERFICIES QUE SE MIRAN ENTRE SI PARALELAS (32, 34). LA ENERGIA LUMINOSA (38) QUE ENTRA EN UNA CAVIDAD DE FABRY-PEROT (36) FORMADA POR ESTAS SUPERFICIES (32, 34) INDUCE UNA FORMACION PERIODICA Y LIBERACION DE ENERGIA EN LA CAVIDAD (36) DIRECTAMENTE RELACIONADA CON LA FRECUENCIA RESONANTE NATURAL DE LOS PUENTES (22, 24). EL ANALISIS DE LA INTENSIDAD DE LA LUZ EMITIDA (50) DESDE LA CAVIDAD (36) DETERMINA LA FRECUENCIA NATURAL DE LOS PUENTES.
