The 254-page book Polarization Holography reviews research carried out in the field over the past 15 years. The authors cover basic concepts in polarization and the propagation of light through anisotropic materials and present a theoretical basis for polarization holography. Materials used in the process are described. Various applications, including display holography and optical storage, are discussed in depth. L. Nikolova and P.S.
