基于随机调制光的计算鬼成像实验研究

鬼成像在远距离遥感、生物医学成像等领域具有重要应用前景。本文以数字光投影仪作为空间光调制器调制产生结构化随机调制光,以此随机调制光为光源,搭建实现计算鬼成像实验装置,实验实现计算鬼成像,分析研究测量帧数对成像信噪比的影响,实验发现测量帧数为2000,4000,6000,8000时,对应成像信噪比分别为0.933、1.296、1.578、1.791,也即表明随着测量帧数的增加,成像信噪比越大。该结果有助于增进对计算鬼成像实验的理解,促进鬼成像在远距离成像包括遥感成像中的应用。

Ghost imaging has potential application in long-distance imaging and biomedical imaging et al.In this paper,we employ the structured random modulated light as the source which is generated by the digital light projector acting as spatial light modulator,and then set up the experimental device that performing computational ghost imaging.We find experimentally that when the number of measurement frames is 2000、4000、 6000、8000,respectively,the corresponding signal-to noise ratio is0.933、1.296、1.578、1.791,which shows that as the increase of measurement number,the signal-to noise ratio of the image increases.This result is helpful to deepen the understanding of computational ghost imaging experiment and promote the application of ghost imaging in long-distance imaging such as remote imaging.
