摘要
灰度掩模法是一种新的二元光学器件制做方法。研究了并行激光直写高性能灰度掩模的工作原理 ,对空间光调制器 (SML )、精缩投影物镜和二维气浮平台等关键单元进行了分析 ,给出了并行激光直写系统的主要技术指标和初步实验结果。
Gray-scale mask method is a novel way of fabricating binary optical elements. In this paper, the working principle about parallel laser direct writing gray-scale masks of high quality was analyzed. In the parallel laser direct writing system, some crucial units such as spatial light modulator (SLM), projection objective and two-dimensional air-bearing stage were studied in detail. Then its main technical indexes and initial experimental results were provided.
