【摘要】 在加工光楔列阵线聚焦系统时，人为地使各单元楔角与精确的理论值之间存在一定的偏差，以使单元衍射引起的大尺度不均匀性得到改善。文中进行了理论计算和实验验证，在既能改善均匀性，又能保证一定的焦线能量利用率的情况下，给出了合理的偏差数据，为优化均匀线聚焦系统的工程设计提供了必要的依据。更多还原

【Abstract】 The deviations of wedge angles to some extent between the actual value and accurately theoretical value are made purposely during processing the segmented wedge array line focussing system in order to improve the large-scale nonuniformity caused by unit diffraction. In this paper, theoretical calculation and experimental verification are made, and the reasonable deviation datu are given in the case of improving the uniformity while ensuring certain utilization ratio of line focus energy. It provides a necessary basis for the optimization design of uniform line focus system.更多还原
