摘要
理论证明探测光路经散射介质的散射与吸收对计算关联成像造成的影响可以近似等效为乘性噪声而被消除,使用蒙特卡罗方法建立烟幕介质的点光源脉冲响应函数模型,分析了不同状态的烟幕对成像的影响,讨论了穿透烟幕成像的可行性。结果表明,当固有噪声Ni=0时,可忽略散射介质对成像结果的影响。最后,总结了计算关联成像技术穿透烟幕成像性能的适用范围,这为计算关联成像应用提供了一定的参考。
Theoretically,the effect of scattering and absorption in the detected light path on the computational ghost imaging can approximately equal the multiplicative noise,and it can be eliminated.The impulse response function model of the point light source in a smoke screen was established using the Monte Carlo method.The influence of the smoke screen in different states on imaging was analyzed,and the feasibility of penetrating smoke imaging was discussed.Results show that when the intrinsic noise Ni=0,the effect of the scattering medium on the resulting imaging can be deemed negligible.Moreover,the applicable scene of the computational ghost imaging technology in a smoke medium was summarized.The research has important reference significance for computational correlation imaging applications.
