| Abstract: | Considering the non-linear strain of piezoelectric actuator, based on the principle of micro displacement of piezoelectric ceramic, the controlling principle of the cavity length is analyzed. The driving characteristic of piezoelectric ceramic is analyzed on condition of the timing of hardware clock. The non-linearity of piezoelectric ceramic are regulated by adjusting the step voltage of the driving signal. A control system based on virtual instrument is designed. The method of linear is theoretically analyzed and tested. The experiment shows that the measuring system can make the piezoelectric ceramic elongate linearly in its elongation range. |
| Keywords: | lasers piezoelectric ceramic micro displacement driving driving characteristic |
