中文摘要：
针对大横截面室内靶道弹丸测速需求,提出采用一字线激光器作为光源,L形排布的光电二极管阵列作为接收的室内大面积矩形探测区域激光测速光幕构建方法,对光幕面内光能分布均匀性进行理论分析及实验研究。在单个一字线激光器光能分布理论分析基础上,通过实验验证了理论分析的正确性,并对两个一字线激光器拼接作为光源的1m×1m靶面的激光测速靶靶面内光能分布均匀性进行了实测研究,对实验结果进行了分析。该研究成果为实用室内超大面积激光测速光幕靶的设计提供了理论及数据参考。
英文摘要：
In order to meet the requirement of velocity measurement of projectile with large cross-section in indoor shooting ranges,a kind of large sensor area laser screen using semiconductor lasers with linear flare as light source and L-shape arranged photoelectric diode arrays as receiver is put forward,and energy distribution of this laser screen is discussed theoretically and experimentally.Light energy distribution of single linear flared semiconductor laser is analyzed theoretically,and experiment is conducted in order to verify the validity of the theoretical analysis.Light energy distribution experimental research of a 1 m×1 m laser screen using two linear flared semiconductor laser joining together as light source is conducted and experiment results are analyzed.The research can provide theoretical guidance and reference data for practical design of larger area laser screen.
