Polychromatic reconstruction (PCR) is a novel holographic reconstruction method that utilizes a spectrally broad light source for a readout probe beam. It enables us to reconstruct stored images at any desired wavelengths even though the probe wavelength is very different from the recorded one. On the other hand, the broadband spectrum of the probe beam considerably degrades the Bragg selectivity and increases the angular separation between multiplexed holograms, which lowers the storage density in holographic data storage systems. However, such a drawback can be overcome if an additional suitable optical component is used in the imaging system. The readout tolerance in the PCR method is also much larger than conventional monochromatic readout. Such unique and attractive features of the PCR method were numerically and experimentally demonstrated.
