户外聚光测试系统设计

为了提高聚光系统的聚光效率,设计了一种户外聚光测试系统.选二阶菲涅耳聚光系统为测试对象,采用局部测量法测试其性能.利用软件模拟聚光系统的透过率、聚光效率和聚光光斑照度分布,并利用户外聚光测试系统对二阶菲涅耳聚光系统进行实验测试.将模拟结果与实验结果对比发现:二者的光斑分布均匀性比较接近,透过率相差1.800%|聚光效率相差4.346%,主要差异来源于加工误差和测量误差.据此可以为设计和加工提供信息反馈,从而改进加工工艺,提高聚光效率.

Design of Outdoor Concentration Test System

In order to improve the concentration efficiency of optical concentration system,an outdoor concentration test system was disigned.The second order Fresnel concentration system was chosen as the test object,and its performances were tested by localized measurement.Using Tracepro software,transmittance,concentration efficiency and concentration spots of the concentration system were simulated.The second order Fresnel concentration system was experimentally tested by outdoor concentration system.Compared the simulation result with experiment result,it was found that the spots uniformity of the two systems are close,and transmittance differences and differences between concentration efficiencies are 1.800% and 4.346% respectively.The differences of concentration efficiencies mainly come from the manufacturing error and measuring error.So this experimental data can provide information and feedback for the designer and manufacturer of the system to improve the processing technology and raise the concentration efficiency.
