Coded-wavelength multiplex volume holography.
We introduce the technique of coded-wavelength multiplex holography. We encode each wavelength with a discrete angular spectrum of plane waves, so that the total number of multiplexed holographic pages equals the number of wavelengths multiplied by the number of discrete wave vectors at each wavelength. Encoding with different propagation angles further permits one to utilize the properties of grating degeneracy to assemble an image from a mosaic of smaller images and to multiplex such images at different wavelengths.
