Diversos autores han propuesto formas alternas para la obtención de estos parámetros. Sin embargo, la esencia del método ha prevalecido. En este trabajo se plantea un método de extremales, que consiste en medir intensidades máximas y mínimas. El procedimiento consiste en cuatro mediciones directas para la obtención del estado de polarización de la luz, sin la necesidad de utilizar los parámetros de Stokes. Se ofrece una representación matemática alternativa de la polarización elíptica, con base en parámetros que representan directamente la inclinación de la elipse y la relación entre sus semiejes. Se muestran resultados experimentales que se comparan favorablemente con el método tradicional.]]></p></abstract>
