✦ Synopsis
Figure 6 Nonlinearity of PZT Figure 7 Hysteresis of PZT actuator which was controlled by a DrA converter. Many experiments have been done to test the PZT. A typical sample PZT is made of 30 pieces, and its radius is 10 mm. The curves of nonlinearity and hysteresis are shown in Figures 6 and 7. Its nonlinearity is 5.8%, and its hysteresis is 16.7%. Its extension is 2.38 m at a voltage of 20 V; it will be w x used in the phase-shifting interferometer 5 .
