Abstract

Here we propose a non-line-of-sight (NLOS) tracking scheme using only one single-pixel single-photon channel. It is demonstrated that sending multiple beams with proper time delay enables multiplexing of multi-echoes of the hidden object in the single channel. Based on the multiplexed temporal histograms, we achieve a retrieval of the object's position with centimeter precision. The experiment of following the target's linear motion is also performed, proving that our technique can reliably track the moving object. This time multiplexing-based NLOS tracking scheme provides a simple way to reduce the numbers of the detecting channels, which may contribute to low-cost NLOS applications.

利用单个时间复用通道进行非视距目标跟踪

在这里，我们提出了一种仅使用一个单像素单光子信道的非视距（NLOS）跟踪方案。实验证明，发送具有适当时延的多波束可以在单通道中复用隐藏对象的多回波。根据多路复用的时间直方图，我们可以精确地检索到目标的位置。我们还进行了跟踪目标线性运动的实验，证明我们的技术可以可靠地跟踪运动物体。这种基于时间多路复用的 NLOS 跟踪方案提供了一种减少探测信道数量的简单方法，可能有助于低成本 NLOS 应用。
