摘　　要：给出均匀透明物体经透镜成像后观察面上的光场分布公式,计算了焦距和二倍焦距处观察面上的光波复振幅和光强。结果表明,焦点处观察面上的光场分布函数为一脉冲函数,而在二倍焦距处观察面上的光场与物体后表面的光场分布函数仅相差一个位相因子。The formula of optical field distribution of the images of the even transparent object lenses is obtained. The complex amplitude and optical intensity of optical field at focal plane and two focal length plane are calculated. The results show that the distributing function of optical field at focal plane is a pulse function, and different from the back plane of the object, only a phase factor, at two focal length plane.
