摘　　要：本文提出一种在水雾环境下进行全息成像的方法。该方法采用波长处于“大气窗口”的红外激光器,通过实验模拟出雾气环境,以探究不同雾气浓度对红外光的全息成像效果影响,并设置可见光数字全息实验作为对比。通过对比红外光与可见光重建图像的不同图像质量评估参数,结果表明该系统红外光可清晰成像,而可见光数字全息系统则成像效果不佳。此外,由于红外光透水雾全息重建像受零级与散斑影响严重,本文对得到的全息图重建像进行消零级与增强Lee滤波去噪声处理,以达到改善图像质量的目的。In this paper,a holographic imaging method in a water mist environment is proposed.Firstly,an infrared laser with a wavelength in the"atmospheric window"is adopted,and the fog environment is simulated through experiments to investigate the effect of different fog concentrations on the holographic imaging effect of infrared light,and set up a visible light digital holography experiment for comparison.By comparing different image quality evaluation parameters of the reconstructed images of infrared light and visible light,the results show that the system can be clearly imaged by infrared light,while the visible light digital holography system has poor imaging performance.In addition,since the holographic reconstruction of infrared light through water mist is seriously affected by the zero level and scattering,the hologram reconstruction obtained in this paper is processed by eliminating the zero level and enhancing Lee filtering to remove the noise,in order to achieve the purpose of improving the image quality.
