The hysteresis of piezoelectric transducers has significant impact on precise control systems. At present,the common methods of piezoelectric transducers hysteresis measurement have some disadvantages such as low accuracy and complex system,so they are difficult to realize high accuracy measurement. The current measurement methods of PZT were analyzed. The hysteresis of piezoelectric transducers was measured and analyzed based on microchip laser feedback interference system by using the scattered light on the surface of the object. The laser frequency-shifted feedback system does not need the target mirror,which means low demand for the measured target. It also has some advantages such as convenience and high resolution of nanometer level. The measurement method has significant guidance for piezoelectric transducers calibration in precise control systems.
