Piezoelectric drive has been widely used in the field of microelectronics and precision machinery. In order to take advantage of the high precision and high response speed of piezoelectric ceramic objective lens drivers, control technology is the core of the control system. The control technology drives the microscope objective lens, which can achieve the relative step micro-displacement between the microscope objective lens and the stage with high accuracy.

In digital confocal microscopy, in order to obtain accurate, equally spaced images of biological cell sequence slices, acquisitions need to be performed by driving a relative step micro-displacement of tens of nanometers between the microscope objective and the stage. The piezoelectric objective control technology is used to drive the objective lens of the microscope to realize the relative step displacement of the objective lens and the stage. Because the stepping motor is driven by a signal to control the mechanical device, there is a certain gap between the mechanical result and the contact surface, and its accuracy can only reach hundreds of microns. Therefore, in order to obtain the accuracy of collecting cell sections by using a bun microscope, an objective lens composed of piezoelectric ceramics is used.
