【摘要】 本文利用菲涅耳衍射理论对一维弯曲光栅的泰伯效应进行了研究.理论分析了一维弯曲光栅的菲涅耳衍射,得到衍射场的一般表达式,预言了借助光栅的弯曲和透镜的会聚可得出光栅放大、等大和缩小的像,数值模拟的结果给出了相应的验证.更多还原

【Abstract】 We analyze the Talbot effect of a curved grating. The magnified,equal and compressed images of the curved grating are obtained with the help of the lens. Based on the scalar diffraction theory,the general expression of the Fresnel diffraction of the curved grating is derived,and the corresponding demonstration is given by the numerical simulation. This is of great help to the development and application of the Talbot effect in the future.更多还原
