摘要：

A general formalism for multiplexed holographic image storage is described which includes both phase and angular encoding techniques. A combination of both methods can easily be treated as well. We derive an expression for the spatial modulation of the refractive index after storage of all images, calculate the diffraction amplitude during readout and deduce the conditions for selective readout. For phase encoding, general rules for the construction of orthogonal phase codes are developped.
