We consider classical second-order ghost imaging with uniformly partially polarized electromagnetic beams and examine the effect of the degree of polarization of the incident light on the visibility of the image. Closed-form expressions for two previously proposed definitions of visibility are derived. Both results are physically similar and show that the visibility increases with the degree of polarization. Hence, a polarized beam is superior to an unpolarized one to obtain a high-visibility ghost image. Some related issues in recent literature are also addressed.
我们考虑了使用均匀部分偏振光的经典二阶鬼成像，并研究了入射光的偏振度对图像可见度的影响。推导出了之前提出的两种可见度定义的封闭形式表达式。这两个结果在物理上是相似的，表明可见度随偏振度的增加而增加。因此，为了获得高可见度的鬼像，偏振光束优于非偏振光束。还讨论了最近文献中的一些相关问题。
