摘　　要：本文讨论了均值估计数字处理技术在光时域反射测量应用中的基本物理过程、数理统计原理、计算机有限字长和触发脉冲存在相位颤动的效应以及基本性能的评价。文后还举例用数据表明采用字长16位小型计算机的数字均值估计处理技术,其性能远优于采用取样积分器的短项积分模拟处理技术。In this paper the basic physical process, mathematical statistics, the effects of finite register length and trigger phase jitter, and the basic performance evaluation in digital averaging estimation processing techniques are discussed in detail for the application in the optical time-domain reflective measurements. Meanwhile it is demonstrated with the data of an example that the performances of digital averaging estimation processing techniques employing 16-bit word length minicomputer are far more better than the boxcar averager analog processing techniques.
