Experimental Study of Two-dimensional Orthogonal Segmented Wedge Array Optical System Applied to Uniform Illumination of Large Focal Spot

提出了一种二维正交光楔列阵均匀照明系统.可将非均匀分布激光光斑变换为尺寸连续可调分布均匀的方形光斑.报道了该系统的设计原理及实验研究结果.并对用于小焦斑均匀照明的可行性进行了论证.

A two-dimensional orthogonal segmented wedge array (SWA) optical system for uniform illumination has been proposed for the first time, which enables us to transform a non-uniform laser spot into the rectangular uniform one with variable dimension. The design principle has been given and experimental results are reported and analysed. The further application to uniform illumination of the comparatively small focal spot has been discussed too.
