APPLICATION OF LISSAJOUS FIGURES IN DETECTING SYSTEM
李萨如图形在检测系统中的应用

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 dynamic characteristics of a second order acceleration measurement system with inertial mass, spring and damping, where the Lissajous figures are used to detect the dynamic characteristics of the force balance acceleration sensor, i.e. amplitude response and phase response. The natural frequency $\omega _{n}$ and damping ratio $\xi $ of the sensor are determined in order to assess the overall performance of the sensor.
