The method of recording data in a volume memory determines the spatial frequency content. We use a three-dimensional transfer function approach to show that this has serious implications for the choice of readout system. In particular, one cannot use a reflection confocal system to read a photopolymer-based memory. A solution to this problem is proposed.
