| 摘 要： | 用视轴对称球面Z视场作为模拟体腔凹面的模型,通过辐射传递特性分析,把最终的边缘光效分解成内部作用和外部作用两大部分,确立了外部作用的边缘光效定义.运用光度学理论推导医用硬性内窥镜照明和成像两光路的边缘光效表达式及外部作用的边缘光效通式.在设定球面Z为理想漫射面的基础上,导出最终边缘光效的计算通式.

| Abstract: | Using view axes symmetrical sphere Z as the modal,the body concave characteristics were simulated and the analysis base was established.According to the analysis of radiance transferring characteristics,the final relative effect of edge light luminosity into two parts as internal and external functions was analyzcd.The definition of external function′s relative effect of edge light luminosity was proposed.Using photometry and optics theory the expression and meaning of two parts of the medical rigid endoscope itself as illumination and imaging routes′ relative effect edge light luminosity was derived.The formula of external function′s relative effect on edge light luminosity,the calculation formula and measurement method of the final relative effect of edge light luminosity on the assumption were given,too. |
