摘要
由于水下环境中存在着复杂的物理过程,如吸收、散射和噪声,因此使用传统的相机成像技术获取高质量图像具有挑战性。鬼影成像具有很强的抗干扰能力,能有效获取水下环境中的图像。在此,我们提出了基于 M2 有序激光模式模式物理模型的鬼影成像框架,并将其应用于鬼影成像。仿真结果表明,激光模式斑点鬼影成像技术即使在较低的采样率下,特别是低于 0.64% 的采样率下,也能重建整个被困轮廓。当采样率为 5%时,使用激光模式斑点鬼成像技术可以获得峰值信噪比为 19 dB 的高质量图像。即使相对随机噪声为 1.0%-5.0%,当采样率一致时,激光模式斑点鬼成像的成像质量也优于随机斑点模式鬼成像、沃尔什斑点模式鬼成像和哈尔斑点模式鬼成像。我们在浑浊水环境中的实验结果证实了模拟结果得出的结论。所提出的激光模式斑点鬼成像技术可作为一种成像解决方案,用于具有挑战性的液体环境,如浑浊液体、恶劣天气和生物组织液。Mochou Yang 及其同事描述了一种基于激光模式斑点模式的鬼影成像框架,它能在低采样率下提高成像质量。他们在浑浊的水环境中演示了这种方法的可行性。
A ghost imaging framework based on laser mode speckle pattern for underwater environments
Due to the complex physical processes found in underwater environments, such as absorption, scattering, and noise, it is challenging to obtain high-quality images using conventional camera-based imaging techniques. Ghost imaging possesses strong anti-interference capabilities and can effectively obtain images in underwater environments. Here, we propose a ghost imaging framework based on a physical model of M2-ordered laser mode patterns and apply it to Ghost Imaging. The simulation results show that the Laser Mode Speckle Ghost Imaging can reconstruct the overall trapped contour even at a low sampling rate, specifically below 0.64%. A high-quality image with a Peak Signal-to-Noise Ratio of 19 dB can be achieved using the Laser Mode Speckle Ghost Imaging when the sampling rate is 5%. Even with a relative random noise of 1.0%–5.0%, the imaging quality of Laser Mode Speckle Ghost Imaging is superior to that of Random speckle pattern Ghost Imaging, Walsh speckle pattern Ghost Imaging, and Haar speckle pattern Ghost Imaging when the sampling rate consistent. Our experimental results in a turbid water environment confirm the conclusions drawn from the simulation results. The proposed Laser Mode Speckle Ghost Imaging can be used as an imaging solution in challenging liquid environments, such as turbid liquids, inclement weather, and biological tissue fluids. Mochou Yang and colleagues describe a a ghost imaging framework based on laser mode speckle pattern which improves imaging quality at low sampling rate. The feasibility of this method is demonstrated in a turbid water environment.
