APPLICATION OF LISSAJOUS FIGURES IN DETECTING SYSTEM

Lissajous figures can be used to detect the phase shift of two signals with a same frequency. This paper introduces a analysis method for determining dynamiccharacteristics of a second order acceleration measurement system with inertialmass, spring and damping, where the Lissajous figures are usedto detect the dynamic characteristics of the force balance accelerationsensor, i.e. amplitude response and phase response. The naturalfrequency \omega _n and damping ratio \xi of the sensorare determined in order to assess the overall performance of the sensor.
