    • Runout characterization is performed on a moving body by positioning a light source and optical sensor at a nominal distance from the moving body, with a beam directed from the light source against a surface of the moving body. The reflected light is detected at a sampling rate with the optical sensor as the moving body moves, and a data stream of the measurements over time is stored. In the case where an interferometer is used as the optical sensor, relative distance measurements are made. The data stream is analyzed to detect repeating signatures in the data stream, where the signatures represent features on the surface of the moving body. At least one of the features is selected as a reference, and the data stream is processed into segments based on the reference, where each segment represents one period of motion of the moving body. The data segments are overlaid on top of each other to produce ordered sets of data points within the segments. Each ordered set of data points is individually averaged and reported as repeatable runout. The average of each ordered set of data points is subtracted from the data points of each set to produce normalized ordered sets of data points. The variances within the normalized ordered sets of data points are reported as a measure of the non-repeatable runout of the moving body.
    • 通过将光源和光学传感器定位在距离移动体的标称距离处,通过从光源引导的光束抵靠移动体的表面,在移动体上执行径向表征。 随着移动体移动,光学传感器以采样率检测反射光,并且存储随时间的测量数据流。 在使用干涉仪作为光学传感器的情况下,进行相对距离测量。 分析数据流以检测数据流中的重复签名,其中签名表示移动体的表面上的特征。 选择至少一个特征作为参考,并且基于参考将数据流处理成段,其中每个段表示移动体的一个运动周期。 数据段被叠加在彼此之上,以在段内产生有序的数据点集。 每个有序的数据点集合被单独平均,并被报告为可重复的跳动。 从每组的数据点中减去每个有序数据点集的平均值,以产生归一化有序的数据点集。 归一化的有序数据点集合中的方差被报告为移动体的不可重复跳动的度量。
