摘要
提出了一种制作四焦点全息透镜的全新光路。对设计原理进行了分析和验证。清除了多余的干涉条纹，从而抑制了重现时的杂散光点。并采用八光路同时曝光，一次形成四焦点全息透镜的方法，提高了衍射效率。
A newest recording path system for gecnerating the four focus hololens is presented.Principles of design are analysed and tested.Unnecessary fringes are cleared away.Thereby some stray light points at reconstuction time are restrained.And adopting a method of eight light beam exposure at the same time forms four focus hololens so that diffraction efficiency is increased.Real optical path system and experimental results are given.
