柱面光栅Talbot效应

TALBOT EFFECT OF CYLINDRICAL GRATING

本文在傍轴近似下,导出了柱面波照射下柱面光栅的Talbot自成象一般公式。它与在球面波照射下平面光栅的自成象规律类似。此一般公式在极限情况下,可退化出已知的平面光栅成象公式。

In this paper, a general formula of Talbot selfimaging on cylindrical grating illuminated by cylindrical wave is derived. At the limit condition, the ordinary formula of self imaging on plane grating can be obtained. The main results in this paper are: The general formula of Talbot self imaging on cylindrical grating is similar with that of Talbot self imaging on plane grating illuminated by spheric wave. The Talbot self imaging on cylindrical grating is a kind of three-dimensional suspension image.
