圆径向相位光栅复制方法研究

Study for method of reproducing radial phase grating

利用4f傅里叶交换系统,通过频谱面滤波手段,将圆盘玻璃振幅型径向光栅复制成全息式相位径向光栅.所复制的相位光栅具有新的频谱信息.另外,还可得到倍频光栅,理论分析和实验结果相符合.

The holographic radial phase and frequency double gratings are reproduced by means of filtering in 4f Fourier transform system. New information of the frequency spectrum is contained in the replicate gratings. Theoretical analysis is in conformity with experimental result.
