Title (EN) CIRCULAR BIREFRINGENCE IDENTIFICAITON OF MATERIALS
(FR) IDENTIFICATION DE BIRÉFRINGENCE CIRCULAIRE DE MATÉRIAUX
Abstract:
(EN) An optical system uses a sample medium disposed within an optical cavity, receives an input beam that may be non-coherent or coherent, and produces an optical energy from the input beam, by creating birefringent-induced beam components each cavity traversal, forming a mixed quantum state beam for the input beam. The mixed quantum state beam exits the cavity, and the energy distribution of the exiting beam is analyzed over a range of tuned input beam frequencies to uniquely identify circularly birefringent the materials within the sample medium, e.g., amino acids, proteins, or other circular birefringent molecules, biological or otherwise.
(FR) Selon la présente invention, un système optique utilise un milieu d’échantillon disposé à l’intérieur d’une cavité optique, reçoit un faisceau d’entrée qui peut être non cohérent ou cohérent, et produit une énergie optique à partir du faisceau d’entrée, en créant des composantes de faisceau induites par biréfringence, chaque traversée de cavité, formant un faisceau d’état quantique mixte pour le faisceau d’entrée. Le faisceau d’état quantique mélangé sort de la cavité, et la distribution d’énergie du faisceau sortant est analysée sur une plage de fréquences de faisceau d’entrée accordées pour identifier de façon unique des matériaux à biréfringence circulaire dans le milieu d’échantillon, par exemple, des acides aminés, des protéines ou d’autres molécules, substances biologiques ou autres à biréfringence circulaire.
