纯相位物体的鬼成像(英文)

Ghost imaging with pure phase object

鬼成像因为其具有的非定域特性和突破衍射极限的高分辨率引起了人们的广泛关注。研究了光源的强度波动对纯相位物体的鬼成像的影响。用理论分析和仿真实验证明了光源的强度波动可以影响鬼成像中纯相位物体的信息:光源的强度波动越大,可以从鬼像中得到的物体信息就越多。同时,发现了随着光源强度波动的增大,不同的采样样本得到的纯相位物体的鬼成像中物体信息的差别越大。

Ghost imaging has attracted a great deal of attentions due to it＆#39;s nonlocal characteristic and imaging resolution breaking the limitation of diffraction. A study about the relationship between the pure phase object ghost imaging and the fluctuation of the source was reported. That the intensity fluctuations of the source can affect the information of the pure phase object which we get from the ghost image was demonstrated theoretically and experimentally： the more severely the intensity of the source fluctuates, the more information of the pure phase object we can recover from the ghost image. Moreover, the increase of the intensity fluctuations could lead to the growing deviation of the object information of ghost images which obtained from different samples.
