摘要

近代的物理學對於光的統計性質有了量化的討論。為了從空間和時間的變數去區別不同的光而有了一階和二階…等相關性的物理量引入。
由於我們人眼和攝影機偵測到的影像皆為光強度分佈的結果，因此我們引入光的二階相關性探討我們看見的影像資訊是來自於同一圖像資訊還是由許多圖像資訊所構成的。
為了解決此問題我們使用了偽熱光源的鬼影像實驗設置與傅立葉轉換在相空間的特性，將來自於不同圖像和資訊藉由光的二階相關性區別開來。
我們將呈現理論模擬及實驗的結果。

In the recent physical region, we found physical quantity to calculate the light of
statistic.
In order to identify the light from the variable of space and time, we calculated the
light of statistical quantity, first order correlation; second order correlation, etc.
Because what we saw and what the charge-coupled device cameras detected were
light of intensity, we introduced the second order correlation to know what we saw
were came from one image or superimposed of many different images.
Therefore, we tried to modify the experimental setup of the pseudo-thermal ghost
image and propose the feature of Fourier transformation in Fourier space in order to
resolve the overlapping image and blurred image by the second order correlation.
We would show the result of the simulation and the experiment.
