摘要
文中提出了一种高密度光变图像的存储方法,利用光变图像激光光刻系统,采用空间光调制器(SLM)进行子图输入,在平面记录材料光刻胶上进行2D光变图像和文字的光学存储,制成易于复制的浮雕位相型衍射图像。
In the paper,a method of optical variable devices storage with high storage density is proposed.Using digitalized laser printing system with the spatial light modulator (SLM)used as the sub-image input device,2D optical variable devices and letters are stored in the plane recording medium photoresist,which can be made into easily reproduced relief phase hologram.
