Abstract

LA INVENCION TRATA DE UN INTERFEROMETRO POLARIZADO Y QUE TIENE UN COLIMADOR PARA LA FORMACION DE UN RAYO DE LUZ POLICROMADO Y PARALELO. TAMBIEN DISPONE DE UN PRIMER ELEMENTO POLARIZADO EN SUS EXTREMOS, EL CUAL POLARIZA AL RAYO DE LUZ PARALELO. TAMBIEN DISPONE DE UN ELEMENTO BIRREFRINGENTE, EL CUAL ESTA DE FORMA VERTICAL HACIA EL RAYO DE LUZ POLARIZADO Y PARALELO. CONSTA ADEMAS DE UN SEGUNDO ELEMENTO POLARIZADO EN SUS EXTREMOS FINALES, EL CUAL POLARIZA LA LUZ SALIENTE DEL ELEMENTO BIRREFRINGENTE Y DE UN DETECTOR DE FOTONES, DONDE EL ELEMENTO BIRREFRINGENTE ESTA COLOCADO DE FORMA OPUESTA Y DESPLAZABLE Y CONSTA DE DOS SUPERFICIES LATERALES Y LONGITUDINALES OPUESTAS ENTRE SI, FORMANDO CUÑAS OPTICAS QUE SE UNEN EN UN RECTANGULO Y DE UNA PLACA DE CARAS PARALELAS BIRREFRINGENTES QUE SIRVEN COMO COMPENSADOR. EL EJE OPTICO DEL COMPENSADOR GIRA ALREDEDOR DE UN ANGULO FINITO FRENTE A AMBAS CUÑAS DEL PLANO VERTICAL QUE VA HACIA EL RAYO DE LUZ. LOS EJES OPTICOS DE AMBAS CUÑAS CONCUERDAN ENTRE SI Y LOS EJES OPTICOS DE LOS POLARIZADORES ESTAN DE FORMA VERTICAL O PARALELA ENTRE SI Y NO DE FORMA PARALELA HACIA LOS EJES DE AMBAS CUÑAS DEL ELEMENTO BIRREFRINGENTE. EN LA TRAYECTORIA DE LOS RAYOS, DETRAS DEL SEGUNDO POLARIZADOR Y DEL DETECTOR DE FOTNOS ESTABLECIDO PARA EL ANALISIS DEL INTERFEROGRAMO, SE ENCUENTRA UN DISTRIBUIDOR DEL RAYO QUE FORMA PREFERIBLEMENTE EL SEGUNDO ELEMENTO POLARIZADO A MODO DEL DIVISOR DEL RAYO POLARIZADO, QUE TIENE COLOCADO UN FILTRO JUNTO CON UN DETECTOR PARA LA MEDICION DEL CAMBIO DE LONGITUD DE LA VIA OPTICA, PREFERIBLEMENTE, UN FILTRO DE INTERFERENCIAS DE BANDA ESTRECHA.
