Systems and methods for measuring twist on a shaft of a rotating drive system include a first set of targets circumferentially distributed around the shaft at a first axial location to rotate with the shaft and a second set of targets circumferentially distributed around the shaft at a second axial location to rotate with the shaft. The first and second sets of targets are interleaved. The system includes a sensor assembly including one or more sensors mounted around the shaft and configured to detect the first and second sets of targets as the shaft rotates. The system includes a sensor processing unit for receiving an electrical waveform from the sensor assembly, determining, based on the electrical waveform, a twist measurement of twist motion between the first axial location and the second axial location on the shaft, and determining, based on the electrical waveform, a second measurement of shaft motion.
