This paper firstly introduces the fundamentals of varifocal optical system, and describes the design of the varifocal optical systems based on optical compensation and mechanical compensation. Then, it elaborates the type and structures of common focusing mechanisms and analyzes their advantages and disadvantages. It points out that along with the DSP control technology and stepping motor development, the varifocal optical mechanism has entered a new prospect. By making a reference to domestic and international engineering applications, the research shows that the numerical control technology based on stepping motors and DSP has an extensive forecast on varifocal optical mechanisms in the range equipment.
