在这篇文章中，我们提出了一个实施的扩展卡尔曼滤波器（EKF）的光学和几何性质的检索在两层混浊介质假设一个动态的设置，其中每一层的吸收在不同的步骤中发生变化。先前的工作实现了EKF在频域与几对光源和检测器和静态参数估计问题。在这里，我们探讨使用EKF在单距离，时域测量，以及相应的前向模型。结果表明，检索和标称值之间的良好协议，具有相当窄的分析可信区间，表明回收过程具有较低的不确定性，特别是吸收系数。
In this article we propose an implementation of the extended Kalman filter (EKF) for the retrieval of optical and geometrical properties in two-layered turbid media assuming a dynamic setting, where absorption of each layer was changed in different steps. Prior works implemented the EKF in frequency-domain with several pairs of light sources and detectors and for static parameters estimation problems. Here we explore the use of the EKF in single distance, time-domain measurements, together with a corresponding forward model. Results show good agreement between retrieved and nominal values, with rather narrow analytical credibility intervals, indicating that the recovery process has low uncertainty, especially for the absorption coefficients.
