中文摘要 | 攝錄影機(DVC)的發展日新月異,它的解析度及像素的容量不斷的提升,由於它多功能化似乎成為人們不可缺少的一個電子產品。本文的初始的設計以四群組成二群移動的理想透鏡組,其中不考慮一階及三階象差,首先取得光學變焦的初始結構。進而選擇合適的透鏡組組成一個實際的四群光學變焦結構,利用光學軟體優化降低像差成份進而達到規格的需求。此設計利用三個非球面及11透鏡組,所以鏡片數及群數的減少,不但成像品質在變焦過程維持固定,且可以降低生產成本的價格。 |
英文摘要 | The evolution of the digital video camcorder(DVC) changes very fast during passing day. Its resolution and pixels number of the capacity will continuous development. According to its multi-function, it becomes people's indispensability of an electron product. The paper design start point with a four-group the paraxial lens set with two groups lens of movements, among the first order and three order aberration is ignored. The imprimis acquisition optical zoom focal length start the structure. Then select the suitable and anastigmatic set to constitute a physical's four group of optical zoom lenses structure. Making use of the optical software excellent turn to reduce the aberration pass muster specification of requirement. This design makes use of three aspheric lenses and 11 lenses sets. The decrease of the lens number and the group number. Not only image quality at focal variation process to support fixedly but also its production cost can reduce. |
