Figure 1 | Conceptual design and operation of the CPOW method-based precise motion tracking and velocimetry.  The Michelson interferometer-based measurement system detects the motion displacement trajectory of high-speed operating devices by precisely identifying the variation patterns of the CPOW in the interference signals. The abbreviations in the image are provided as follows. dispersion-compensating fiber (DCF), collimator (Col), beam splitter (BS), photodetector (PD), oscilloscope (OSC), and personal computer (PC).
