Abstract: Systems and methods for perturbation analysis of harmonic oscillations in the time domain according to several embodiments can include a time domain switching sensor and a resonator for imposing a first oscillation and a second oscillation on the sensor. The first and second oscillations can have the same amplitude A and period P, but can have a known phase shift. The sensor can use a time interval, which can be defined by the time between when the sensor passes a reference point due to motion caused by the first oscillation and when the sensor passes the same reference point, but due to motion caused by the second oscillation. With this configuration an improved accuracy of measurement for the system can be realized.
