今天,在这里再展开说一下,说明测量透镜焦距之前首先介绍下泰伯效应(Talbot effect)。 图1. 光线通过周期结构,图片来自https://en.wikipedia.org/wiki/Talbot_effect 简单说,泰伯效应就是一个波长为λ的平面波照射在周期结构(光栅),在特定的位置处会形成周期结构(光栅)本身的像,而这些特殊位置处就在zm=2mΛ2λ,...

泰伯效应（Talbot effect）是一个光学现象，于1830年由Talbot发现。该效应描述了当单色平面波垂直照射一个周期性物体时，在物体后面一定距离上会周期性地出现物体的像。这个现象称为自成像，且在特定距离上会重复出现原始物体的像。其中，这些像的出现遵循泰博距离公式，即在整数倍的泰博距离上会出现原周期...
Talboteffect •泰伯效应（又译为塔尔博特效应）是光栅在相干光照明下在自由空间中某些特定的距离Z处自成像的现象。•分数泰伯效应或称分数泰伯自成像是指这种成像过程发生在Z的分数距离上,如Z/2处,Z/3处等等。Talboteffect的傅立叶变换解释 •以最简单的Ronchi（朗奇）光栅为例：一周期为d的光栅为（此处脚...
