光学中的Bessel函数与Sinc函数

Bessel Function and Sinc Function in Optics

利用Bessel函数和Sinc函数的性质,讨论夫琅禾费圆孔衍射和单缝衍射各级条纹内的能量分布。

In this paper, it is discussed that the distribution of energy in pattern of Fraunhofer circular hole diffraction and single slit diffraction by means of properties of Bessel function and Sinc function, and proved that the relative energy in zeroth order pattern of single slit diffraction is more than that in Airy disk.
