Abstract
A general formalism for multiplexed holographic image storage is descr ibed which includes both phase and angular encoding techniques. A comb ination of both methods can easily be treated as well. We derive an ex pression for the spatial modulation of the refractive index after stor age of all images, calculate the diffraction amplitude during readout and deduce the conditions for selective readout. For phase encoding, g eneral rules for the construction of orthogonal phase codes are develo pped.
