Stratified Volume Holographic Optical Elements
In this method, the distributed optical inhomogeneities that characterize a typical hologram are approximated by a discrete sequence of physically and mathematically simplified elements: infinitesimally thin phase and/or polarization modulation layers, interleaved with optically homogeneous layers of finite thickness. By approximating the distributed grating with a sufficiently large number of these discrete elements, the resulting numerical model of the grating can be brought arbitrarily close to that of the desired distributed bulk grating.
