Abstract

We have been investigating a new type of optical data storage media using three-dimensional diffused object. The data is stored as three-dimensional absorbers in a highly scattering medium. The scattering medium can protect the absorbers because it blurs the light distribution. To recover the absorption distribution, the scattering coefficient distribution of the medium is required. We present an algorithm to recover the 3D absorption distribution to decrease the calculation time. Numerical evaluation of the proposed algorithm and the storage capacity are discussed.
