标题： Spectral Method for Multiplexed Phase Retrieval and Application in Optical Imaging in Complex Media

摘要： 我们引入了一种称为多路复用相位恢复的相位恢复的广义版本。 我们希望从它们的线性组合中恢复仅具有幅度的测量值的相位。 这对应于多个非相干光源被联合采样的情况，人们希望恢复它们各自的贡献。 我们表明，一种最近为相位恢复开发的谱方法可以推广到这种设置，并且其性能表现出相变行为。 我们将这种新技术应用于复杂介质中的深度光聚焦。 实验上，尽管我们只能访问多个目标上强度的总和，但我们能够分别对每个目标进行聚焦，从而在深层荧光成像和光传递方面开辟了潜在的应用。 显示英文摘要

摘要： We introduce a generalized version of phase retrieval called multiplexed phase retrieval. We want to recover the phase of amplitude-only measurements from linear combinations of them. This corresponds to the case in which multiple incoherent sources are sampled jointly, and one would like to recover their individual contributions. We show that a recent spectral method developed for phase retrieval can be generalized to this setting, and that its performance follows a phase transition behavior. We apply this new technique to light focusing at depth in a complex medium. Experimentally, although we only have access to the sum of the intensities on multiple targets, we are able to separately focus on each ones, thus opening potential applications in deep fluorescence imaging and light delivery
