Solutions on global synthesis to improve multiple configurations

Multiple configurations system and its influence and control on aberration are the basis for the design of such systems and have practical value in engineering. The principle, modeling and error analysis are analyzed. Based on the system configuration of the compound zoom system, moreover, this paper advances the algorithm analysis. With an interval which between the elements as the initial amount, the form of motion of the elements is used as the free amount, and the distribution of the optical focal length and the form of the element motion can be obtained by calculating the equation sets. Compared with the traditional method, the global synthesis can significantly improve the design in effect and efficiency.
