An optical recording technique, called retardagraphy, can record a retardance pattern of a birefringent object on a polarization-sensitive medium made of azobenzene copolymer. In holography, a recording laser beam must be split into signal and reference parts. In contrast, it is not necessary for the retardagrapy to split the recording laser beam. This feature simplifies the optical system. The multi-valued phase pattern recorded on the polarization-sensitive medium can be reconstructed by measuring a retardation between two polarization components. The optical recording and reconstructing methods of binary and multi-valued phase patterns are demonstrated by retardagraphy.
