摘要


在變焦鏡頭的領域中,大都著重於傳統式的變焦系統,其變焦方式是讓透鏡沿著光軸移動而改變整體的有效焦距。其缺點是當透鏡移動時若機械公差過大會造成失焦或無法移動。因此針對此缺點改用旋轉變焦的方式。本文嘗試新的設計概念,利用球形變焦透鏡的旋轉來達到變焦的目的,並比較與傳統變焦之間的性能差異。

In the scope of zoom lens, most of researches focus on traditional zoom lens system, which changes the effect focus by moving the lens along optical axis.But as the mechanical tolerance is too much, it is hard to move the lens, and will cause the image blurred.In order to amend this drawback, this research was investigated to change focus by rotating the spheral lens in substitution for the tradition ways and makes comparison of capabilities between them.
