摘要
提出了一种记录多方向全息相位光栅的新光路,详细介绍了此光路的调整方法。采用四光路同时曝光,提高了光栅的衍射效率。给出了有实用价值的实验结果和理论分析要点。
A new recording system for generating the multidirectional holographic phase gratings is presented. An adjusting method of the system is discussed in detail. Adopting a method of four light beam exposure at the same time, the diffraction efficiency of the gratings is increased. Theoretical interpretation of the experimental results is outlined.
