利用激光干涉条纹在偶氮聚合物薄膜上制作了表面浮雕全息图。研究中使用的是侧链偶氮聚合物多橙TOM-1异佛尔酮二异氰酸酯。研究了表面浮雕结构的记录特性，它们不需要后处理，可以通过加热或照射均匀的激光束来擦除。电晕充电显著提高了记录全息图的衍射效率。它也是通过电晕充电的激光(488 Nm)照射控制的。
Surface relief holograms were fabricated on azo-polymer films by the irradiation of interference laser fringes. The side-chain azo-polymer, poly-orange tom-1 isophoronediisocyanate, was used in this study. Recording characteristics of surface relief structures were investigated they needed no post-treatment, and could be erased by heating or irradiating a uniform laser beam. The diffraction efficiency of the recorded hologram was markedly increased by corona charging. It was also controlled by irradiation of the laser beam (488 nm) with corona charging.
