Presentamos una técnica flexible y de bajo coste que permite la producción de elementos ópticos difractivos binarios de fase. Se han obtenido redes de difracción, lentes de Fresnel y filtros para correlación óptica. En un primer paso se han diseñado estos elementos mediante técnicas digitales. La implementación física se ha realizado con una impresora Linotronic, con la cual se han obtenido hologramas binarios de absorción. Estos hologramas se han registrados mediante un proceso de copia por contacto sobre gelatina dicromatada (DCG) y sobre gelatina sensibilizada de haluro de plata (SHSG) y se ha estudiado el comportamiento de ambos materiales para bajas frecuencias espaciales.A flexible and low cost technique that permits the production of...
