摘要

在计算成像领域，如何在更短的时间内获得更好的成像质量始终是一个具有挑战性的问题。功能强大的压缩传感作为一种后端算法，为我们在成像系统中开发压缩方法提供了空间。光学微分技术被广泛应用于直接成像，以突出图像的特征。我们在相关成像系统中应用光学分辨来压缩信息。实验结果表明，信噪比和成像速度都有显著提高。此外，该方案还能通过二阶相关性实现相位成像。我们的研究成果有望应用于生物显微成像和散射介质成像。

Compressed computational imaging based on optical differentiation.

In computational imaging, getting better imaging quality with shorter time usage is always a challenging problem. The powerful compressed sensing functions as a backend algorithm, which leaves room for us to develop a methodology of compression in imaging systems. Optical differentiation was widely utilized in direct imaging to highlight the features of an image. We apply optical differentiation to compress information in the correlated imaging system. The experimental results indicate a significant improvement in the signal-to-noise ratio and imaging speed. In addition, this scheme enables phase imaging from the second-order correlation. Our work can spark potential applications in biological microscopic and scattering media imaging.
