摘　　要：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。The actual concentration performance of deflection trough concentrators was studied based on researchers of the mirror arrays design. The optical path of a specific deflection trough concentrator arrays was analyzed, then it was validated via the experiments by the optical tester and outdoor measurement, the outdoor experiments was com- pleted on 5th November in Nanjing. The conclusion is that the geometric concentration ratio of a single deflection trough concentrator could reach 14-18 times, and it is 50 times to the specific deflection trough concentrators com- posed by five mirrors. The flux concentration ratio is about 60% compared to the geometric. Finally, the methods were analyzed to improve the geometric concentration ratio.
