A novel and effective simultaneous recording method, to the best of our knowledge, is proposed for improving the diffraction efficiency and uniformity of full-color holographic optical elements (HOE) using the Bayfol HX102 photopolymer. To improve the diffraction efficiency of a full-color HOE, it is important to find the optimal recording beam intensity taking into account the initial and late responses of the medium. The range of optimal beam intensity for recording full-color HOE can be found experimentally by analyzing the inhibition period and response characteristics of the recording medium for three wavelengths. Through this method, a full-color HOE with an average diffraction efficiency of about 56.81% and a standard deviation of about 1.7% was implemented in a single layer photopolymer.
据我们所知，提出了一种新颖且有效的同步记录方法，用于使用Bayfol HX102光聚合物提高全彩色全息光学元件（HOE）的衍射效率和均匀性。为了提高全彩色HOE的衍射效率，考虑到介质的初始和后期响应来找到最佳记录光束强度非常重要。通过分析记录介质对三种波长的抑制期和响应特性，可以通过实验找到记录全彩色HOE的最佳光束强度范围。通过这种方法，在单层光聚合物中实现了平均衍射效率约为56.81%且标准偏差约为1.7%的全彩色HOE。
