Abstract We analyse and optimize the exposure-schedule of three-dimensional dynamic-static speckle multiplexing (DSSM) schemes. The uniform diffraction efficiency for the DSSM volume holographic storage system is realized in an ion and indium doped LiNbO3 crystal. An overlap-factor matrix is introduced into the system to compensate for the complex erasure effects caused by the static speckle multiplexing. We obtain 100 holograms demonstrating the exposure-schedule theory. The uniformity of the diffraction efficiency is improved by about 8%.
