研制了一种可连续改变焦线宽纵比的光楔列阵均匀线聚焦系统。线长变化后，焦线宽度、光强分布均匀性、靶面位置仍然不变。实验研究与理论分析结果一致。 A uniform focusing system of optical wedge array with continuously varying focal length and width ratio was developed. After the line length changes, the focal line width, light intensity distribution uniformity, the target surface position remains unchanged. Experimental research and theoretical analysis of the same.
