Method Of Multiple Moving Zoom Lens System Design

With the development of modern technology,the photoelectric tracking measurement system of observation and tracking ability request is higher and higher,and then design of optical system is more and more complex.So zoom structure more and more applied in the photoelectric tracking measurement system.Zoom optical system of the detection precision is high,and its structure is complex.Especially,this paper analyzes the type theory of zoom optical system and zoom cam curve design method for zoom optical system and a multiple-moving zoom lens is designed.First,we present detailed theoretical and experimental analysis of multiple moving zoom optical systems.In our work we propose methods to determine the basic parameters of such optical systems.Based on traditional zoom lens systems structure,in order to optimize optical system multiple moving zoom system reduces number of fixed groups.With Gaussian optics formula and dynamic optical theory,derivation to satisfy equation of zoom optical image stabilization system requirements.The aim of this paper is to perform a detailed theoretical and experimental analysis of multiple optical systems.In the work,we performed a detailed analysis of the imaging properties of multiple moving optical systems of telephoto lenses,and we demonstrate how our analysis can be used in zoom system design to determine the basic parameters of such optical systems.With mathematics method to establish a math model analysis zoom optical systems.Using dynamic optical theory discussed multiple moving zoom system,derived equations of image stabilization,and calculated cam curve,realized of the image motion compensation process,keeping image plane of zoom optical system is relatively stable.Finally an effective focal length 27-270 mm,zoom range is 10 X,F/# number 4~6,and radial fields is 4.2°~33° zoom lens with four groups(three of which are moving)has been designed.Using the powerful optimization capabilities of optical design software CODE V,we get the imaging quality analysis,MTF etc.
