Abstract

Sistema (100, 100') para medir la rotación angular relativa θ de dos planos A y B, que comprende: - una fuente de luz que produce un haz de luz, - un primer subsistema óptico integrado en el plano A para preparar un estado adecuado para el haz de luz; - un segundo subsistema óptico integrado en el plano B para medir el estado del haz de luz que sale del primer sistema óptico; en el que θ es el ángulo en torno a un eje paralelo al haz de luz, caracterizado por que - el primer subsistema óptico comprende, en secuencia a lo largo de la dirección del haz de luz: - medios (QWP, HWP) para producir un estado polarizado linealmente para el haz de luz; - una primera placa q (placa q), que es una pastilla birrefringente con un eje óptico transversal con una estructura adecuada y una singularidad topológica en su centro con una carga topológica asociada q, y está dispuesta para transformar un estado de polarización en un estado de polarización/momento angular orbital; - el segundo subsistema óptico comprende también en secuencia a lo largo de la dirección del haz de luz: - una segunda placa q (placa q) con la misma carga topológica q que la primera placa q, estando dispuesta la segunda placa q para transformar un estado de polarización/momento angular orbital en un estado de polarización; - medios (PBS, APD) para medir la polarización del haz de luz.
