Design Of Zooming Optical System

Zooming optical system is a system in which the focal length can be changed continuously but the image surface position keeps stable. The key point of the zooming optical system design is how to solve the image surface drift problem during the process of zooming.On the foundation of consulting many literatures overseas and home, and combined with work practice, the paper gives the considering method of zooming optical system design.According to Gauss optical theory, the paper analyses detailedly optical compensation method and mechanical compensation method of zooming optical system and explores the general way of zooming optical system design. It analyses the affection of various manufacturing errors to the zooming optical system and an adjusting & calibration method is given.
