%X It is given the formulas to calculate the exposure time in recording uniform multiple-holograms in this paper.The influence of scattering effects on the time constant of photorefractive crystal has been analyzed and so does the influence of light beam couple on grating amplitude.The formulas have been modified by these two influences.The calculated results have shown that the uniform holograms and great holographic grating can be obtained in this exposure schedule.In experiment,we have easily stored thirty uniform superimposed holograms in Fe:LiNbO3 crystal of thickness 0.6mm in the exposure schedule by using angular multiplexing.
