线性菲涅耳不同镜场光学性能比较
|
摘要
首先通过矢量分析,得到线性菲涅耳(LFR)东西场镜场中任意矩形镜元的入射角、反射矢量、跟踪倾角计算公式,然后利用南北场的相关公式,对这两种不同的LFR镜场分布的末端损失、大气衰减、余弦系数等光学效率进行分析比较,针对不同应用,找出合理的镜场分布方式,为LFR系统的大规模应用提供重要的参考与指导。
The formulae of incidence angle,tracking tilt angle and the reflected vector for north-south and eastwest aligned LFR mirror field were presented by vector analysis. Then the different optical efficiency including cosine factor,atmospheric attenuation and end effect for two kinds of LFR mirror field were analyzed and compared by correlation formula of north-south aligned LFR mirror field. Finally,the reasonable LFR mirror field layout mode was recommended in order to fit different application,which will provide important reference and instruction for large scale LFR technology application.
