摘　　要：传统太阳模拟器由于其相对固定结构的制约,输出光斑的大小和形状难以调节。在太阳模拟器中使用了柔性光纤束来传输高强度的光流,并通过CCD(电荷耦合器件)相机等设备测量了不同空间布置下模拟器的输出能流密度分布。研究结果表明通过调整光纤束的空间布置和氙灯功率,可获得特定的光斑形状和能流密度分布,从而实现3D空间内对输出光斑的灵活调整。The size and shape of the output light spot in the traditional solar simulators is difficult to be adjusted due to its relatively fixed structure.This paper used flexible fiber bundles to transmit high-intensity optical flow in the solar simulator,and measured the output energy flow density distribution of the simulator by CCD(charge-coupled device)camera and other devices under different spatial arrangements.The results show that specific spot shapes and energy flow density can be obtained by adjusting the spatial arrangements of optical fiber bundles and the power of xenon lamp,thus realizing the flexible adjustments of output spots in 3D space.
