About the Design of the Optical system of an Orthoprojector

    摘要
  • 摘要: 变焦系统在函数投影类型的正射投影仪中得到了广泛的应用。本文分析了二元变焦核的特性,讨论了应用于正射投影仪的变焦系统的设计思想,并且给出了具有二个变焦系统的设计实例。

     

    Abstract: The zoom system is applied widely in the orthoprojector,working on the principle of the functional or the photographic projection.In this paper the characteristics of the vari-focal kernel with two elements is analysed and the design idea of the zoom system applied to orthoprojectors is described.Futhermore,an example of design with two zooms is given.
