The performance of two-center holographic recording is theoretically studied and described in detail. We present a systematic method for global optimization of two-center holographic recording. Whereas the method presented is general, we perform optimization for lithium niobate crystals doped with iron and manganese (LiNbO<sub>3</sub>:Fe:Mn). Both dynamic range (M/#) and sensitivity (<i>S</i>) are considered for global optimization, and the optimum design parameters for LiNbO<sub>3</sub>:Fe:Mn crystals are predicted. To achieve optimization we use both an analytic approach and a complete numerical approach. The absorption of light in the crystal is also considered. We show that the optimum design parameters for maximizing M/# are different from those for maximizing <i>S</i>. Therefore a trade-off exists between dynamic range and sensitivity. We also describe the complete dependence of <i>S</i> in two-center recording on the design parameters. We show in particular, for the first time to our knowledge, that <i>S</i> depends on the ratio of recording and sensitizing intensities and not on the absolute intensities.
