传输矩阵(TM)描述了当相干波通过散射介质时输入和输出相量场之间的线性关系。TM的测量使得许多应用成为可能,但是对于任意介质来说是具有挑战性的和时间密集的。最先进的方法,包括相移全息术和双相位恢复,需要大量的测量和捕获后重建,这通常是计算密集型的。在本文中,我们提出了3PointTM,用于感测TM的方法,使用最少数量的测量每像素减少了两个因素的测量预算相比,在相移全息术测量TM的最新技术,并具有较低的计算复杂性相比,相位检索。我们验证了我们的方法对真实的和模拟数据,并显示出成功的光的聚焦和图像重建的密集散射介质。
A transmission matrix (TM) describes the linear relationship between input and output phasor fields when a coherent wave passes through a scattering medium. Measurement of the TM enables numerous applications, but is challenging and time-intensive for an arbitrary medium. State-of-the-art methods, including phase-shifting holography and double phase retrieval, require significant amounts of measurements, and post-capture reconstruction that is often computationally intensive. In this paper, we propose 3PointTM, an approach for sensing TMs that uses a minimal number of measurements per pixel—reducing the measurement budget by a factor of two as compared to state of the art in phase-shifting holography for measuring TMs—and has a low computational complexity as compared to phase retrieval. We validate our approach on real and simulated data, and show successful focusing of light and image reconstruction on dense scattering media.
