| 摘 要： | 为了研究全息光栅拍摄过程中曝光对比度与干涉条纹漂移均方根值之间的关系和提高大面积光栅拍摄质量,采用莫尔条纹原理和线阵电荷耦合器件照相机系统组成的条纹锁定系统进行了光栅拍摄实验。对莫尔条纹的漂移量进行了实时采集和分析,发现条纹漂移主要由缓慢漂移和频率为3.1Hz的振动合成。得到了条纹漂移均方根值与光栅曝光对比度之间的数值关系,为预测光栅质量是否合格提供了理论参考。结果表明,要提高光栅拍摄质量,必须保证条纹漂移均方根值小于0.05λ。该条纹锁定系统完全可以满足此要求。

| Abstract: | In order to study the relationship between the contrast of holographic grating and the root mean square(RMS) value of interferential fringe moving,a fringe locking system constituted by Moire fringe theory and charge coupled device camera is used to shot holographic grating.The value of moving Moire fringe is real-time gathered by CCD.It has been discovered that the fringe moving is composed by slowly excursion and vibration of 3.1Hz.And the RMS value of fringe moving is correlated with the contrast of holo... |
