And then , the method for determining the optimum number of batches for fixing a given number of holograms is present based on above research 北京工业大学理学博士学位论文一计算比较了以不同分批数存储热固定的多重全息图的衍射效率。
Furthermore , the exposure schedule for recording holograms with equalized diffraction efficiency is designed based on the above - mentioned optical erasure time constants 并且依据上述两种光擦除时间常数,为分批存储热固定多重全息图的等衍射效率记录设计了曝光时序。
