平均光程是研究光在生物组织等混浊介质中传播的一个重要参数。本文提出了一种简单的减法方法来确定光子在混浊介质中传播的平均路径长度。该方法基于平均时间延迟（即，重心）是仪器函数的平均时间延迟之和（即，测量系统的脉冲响应）和高散射介质的脉冲响应。利用该方法，可以快速准确地计算平均光程长度，而不需要进行反卷积。文中介绍了该方法的理论、计算机模拟和实验验证。
The mean path length is a key parameter in the study of light propagation in turbid media such as living tissues. In this paper, we propose a simple subtraction method for determining the mean path length traveled by photons in turbid media. The method is based on the fact that the mean time delay (i.e., the center of gravity) of the measured re-emission profile is the sum of the mean time delays of the instrumental function (i.e., the impulse response of the measuring system) and the impulse response of a highly scattering medium. Using this method, the mean path length can be calculated quickly and accurately without the need for performing deconvolution. The theory, computer simulation and experimental demonstration are described.
