论文摘要
由于混合光谱点扩散功能在记忆效应范围内的复合物，因此通过宽带照明下的散射培养基将斑点相关技术用于非侵入成像是不可靠的。随着光源的频谱宽度的增加，斑点的对比度将大幅下降。在这里，我们提出了一种在宽带照明下以内存效应范围内的几个斑点框架产生光传递函数的方法。该方法可以应用于白色LED照明下的图像振幅和颜色对象。与宽带照明下的其他成像方法相比，例如深度学习和改进的相位检索，我们的方法可以通过更快的收敛速度提供更稳定的结果，可以在自然光照明下以高速散射成像应用。
Due to the complex of mixed spectral point spread function within memory effect range, it is unreliable and slow to use speckle correlation technology for non-invasive imaging through scattering medium under broadband illumination. The contrast of the speckles will drastically drop as the light source's spectrum width increases. Here, we propose a method for producing the optical transfer function with several speckle frames within memory effect range to image under broadband illumination. The method can be applied to image amplitude and color objects under white LED illumination. Compared to other approaches of imaging under broadband illumination, such as deep learning and modified phase retrieval, our method can provide more stable results with faster convergence speed, which can be applied in high speed scattering imaging under natural light illumination.
