以挠曲柱面聚光理论及镜组设计方法为基础,研究挠曲柱面镜组的实际聚光性能。首先,对一种具体的挠曲柱面镜组的聚光光路进行分析,然后通过室内聚光光路测试仪和室外实测对该挠曲柱面镜组的聚光效果进行实验验证,室外实验在南京地区11月5日完成。得出结论,单列挠曲柱面聚光镜可达到14～18倍的几何聚光比,由五面挠曲柱面镜组成的镜组的几何聚光比可达50倍以上,能流聚光比是几何聚光比的60%,在此实验基础上分析了产生偏差原因以及提高聚光比的方法。
Based on the theory of flexural cylinder focusing and the design of mirror group, the actual condensing performance of flexural cylinder group is studied. First of all, the condensing light path of a specific flex cylinder is analyzed, and then the condensing effect of the flex cylinder is confirmed by the indoor condenser light path tester and outdoor measurement. Nanjing completed on November 5. It can be concluded that single column flexural cylindrical condenser can achieve 14 to 18 times geometric condensing ratio and the geometric condensing ratio of mirror group composed of five side flexing cylindrical mirror can reach more than 50 times. Is 60% of the geometric concentration ratio, on the basis of this experiment analyzes the causes of bias and improve the condenser ratio method.
