通过对二维“鬼”成像的理论和实验分析,探讨了一种新型成像原理和系统,并从理论和实验上利用近红外光源实现了二阶二维“鬼”成像。从光波动经典理论入手,利用完全非相干、均亮的近红外光源对二阶二维“鬼”成像理论进行了详细的分析,推导出其解析表达式,并利用针孔作为被成像物体进行了数值模拟分析。数值模拟结果表明,利用二阶光强度关联成像方法可以精确重现被成像物体。实验上,利用掺饵光纤放大器作为产生非相干近红外光光源,设计并实现了二阶二维“鬼”成像实验。实验结果表明,基于光波动学经典理论的该数值模型所预测的数值仿真结果,与实验结果一致。
Through theoretical and experimental analysis of two-dimensional “ghost” imaging, a new imaging principle and system is discussed, and second-order two-dimensional “ghost” imaging is achieved theoretically and experimentally by using near-infrared light source. Starting from the classical theory of light fluctuation, the second-order two-dimensional “ghost ” imaging theory is analyzed in detail by using a totally incoherent and homogeneous near-infrared light source, and its analytical expression is deduced. The pinhole is used as the imaging The objects are numerically simulated. The numerical simulation results show that the second-order light intensity correlation imaging method can accurately reproduce the imaged object. Experimentally, a two-dimensional two-dimensional “ghost ” imaging experiment was designed and implemented by using a bait fiber amplifier as a source of incoherent near-infrared light. The experimental results show that the numerical simulation results predicted by this numerical model based on the classical theory of light fluctuation are consistent with the experimental results.
