1.全息学中的信息传递大家对全息学都有一定了解,对怎样解释全息学也有一定的了解。我想以另一种方法解释全息,重点讲一下信息的问题。大家先回忆一下相干光里面的成像问题。请看图1,物体是u(x),物体通过透镜到这个面(透镜的后焦面),也就是经过了付氏变换,因此我们在透镜后焦面上得到u(v)。再经过一 1. Holographic information transmission We all have a certain understanding of holography, holographic learning how to explain to some extent. I would like to explain holography in another way, focusing on the issue of information. We first recall the imaging of coherent light inside. Consider Figure 1, where the object is u (x), and the object passes through the lens to this face (the back focal plane of the lens), ie through the Fourier transform, so we get u (v) on the back focal plane of the lens.
