论文摘要
通过散射介质传播的波通常会产生复杂的时间场分布。多年来，已经出现了许多程序来塑造该场的时间剖面，以便将其能量集中在接收器上。通过类似，我们从理论上和实验上证明了如何最大程度地提高传输到接收器的渔民的总信息，以及如何在任何给定时间将Fisher信息集中到。这使人们能够从嘈杂的测量值中估算任何可观察到的物理的值，如超声制度中使用声波实验所示。通过在任意复杂媒体中执行的时间分辨测量值获得的最终精确限制，我们的方法为许多应用程序（例如结构性健康监测和生物医学成像）设定了一般基准。
A wave propagating through a scattering medium typically yields a complex temporal field distribution. Over the years, a number of procedures have emerged to shape the temporal profile of the field in order to temporally focus its energy on a receiver. By analogy, we theoretically and experimentally demonstrate here how to maximize the total Fisher information transmitted to a receiver, and how to focus the Fisher information at any given time. This enables one to estimate the value of any physical observable with optimal precision from noisy measurements, as experimentally illustrated using acoustic waves in the ultrasound regime. By yielding the ultimate precision limit achievable from time-resolved measurements performed in arbitrarily complex media, our approach sets a general benchmark for many applications such as structural health monitoring and biomedical imaging.
