When the piezoelectric actuator receives a step voltage signal, the output displacement collected by the laser displacement sensor is analyzed by the Fourier transform (FFT), as shown in Figure 13.
When the voltage-voltage driver is subjected to a step voltage signal, the output displacement collected by the laser displacement sensor uses the spectrum analysis results obtained by fourleet transformation (FFT), as shown in Figure 13.
