2 December 2010 Retardagraphy: a new polarization recording method and its applications
Author Affiliations +
An optical recording technique, called retardagraphy, has been proposed, in which, retardance distribution of a birefringent object can be recorded on a polarization-sensitive medium made of an azobenzene copolymer. The phase difference distribution between two orthogonal polarization components of the wavefront to be recorded can be directly recorded. The multi-valued phase pattern recorded can be reconstructed by measuring retardation between two polarization components by an imaging polarimetry technique. In this paper, the optical recording and reconstructing methods in retardagraphy are presented. Its application to optical mass data storage is discussed.
