摘要
通过对空间周期性物屏衍射特征的分析与归纳,提出光经空间周期性物屏衍射和自成像的过程,就是光子对物屏的周期性空间信息的记录和再现的过程。根据这一观点,自然地导出了Talbot自成像公式,与采用波动性观点的惠更斯-菲涅耳原理和Fourier变换等传统方法所得结论相同。这样,便于对光子信息传递特征的认识,有助于对Talbot成像中调节参数物理意义的理解。由于数学处理方法简明扼要,该方法易于推广和应用。
Diffractive characteristic for periodic objects was analyzed and generalized. It is suggested that the nature of Talbot self-imaging is the recordation and reappearance for spatial information of object by photons. The formula of Talbot self-imaging is explained by our new suggestion and the same conclusions with Huygens-Fresnel principle or Fourier transform is obtained. With the analysis, the ability of a photon to transfer information could be known well. At the same time, the coefficients of Talbot Formula could be understood well by the method used. Being its simplicity in mathematics, the suggested method is easy to use widely, especially in the fields of Information.
