强吸收弱散射介质下的鬼成像实验研究

为了提高复杂环境下的成像质量,通过鬼成像的方法,设计出相应的实验架构。为了更直观地描述成像质量,引入参数峰值信噪比(PNSR)来具体衡量成像质量。实验结果表明,散射噪声对鬼成像没有影响,同时,在散射不变而吸收性不断增强的情况下,鬼成像相比于传统成像,成像质量更加稳定,抗干扰能力更强。

Experiment study on ghost imaging in strong absorption and weak scattering media

Imaging in the noisy environment is an important issue that has application in diverse fields. In this paper, we use the ghost imaging method to study the imaging quality problem in noisy environment, and design an experimental framework based on ghost imaging. In addition, the peak noisy-signal-ratio (PNSR) is proposed to measure the quality of the imaging in detail. Through the contrast of the imaging quality, the experimental results show that the scattering noise has no effect on the ghost imaging. Under the condition of constant scattering and increasing absorption, the imaging quality of the ghost imaging is more stable than that of the traditional imaging. The ghost imaging is a new imaging method that reduces the impact of noise environment. With the increasing of the absorbance, the advantages of ghost imaging are more obvious to a large extent.
