| 中文摘要: |
| 通过对Zoom闪光灯光学系统的分析,建立了光学系统的数学模型,导出有关公式,并通过编制程序,经计算机计算,得出了闪光灯中的变焦菲涅尔透镜参数及其所处的位置与闪光灯有效照射角的关系。最后得到一组理想的实用数据。 |
| 英文摘要: |
| In this paper, by analysing the optical system of Zoom Flash,a mathematical model of optical system has been established. The calculating formulate have been arrived.By designing and running the calculating program,the relationship between the parameters of Fresnel condenser lens of Zoom Flash and its illuminate angle has been arrived. In the last, a group of ideal optical parameters is given. |
