摘要：

The relationship between refractive index modulation parameters and beam ratio is examined experimentally and theoretically for multiple-exposure holograms, both for the case of simultaneous and sequential recordings. These parameters are determined by measuring the diffraction efficiency of each main grating. Using the measurements, the optimum beam ratio for high efficiency is determined. Experimental results are in good agreement with theory.
