摘要
激光平行光幕用途广泛,可以用来测量物体的直径,弹丸的速度、坐标、弹丸着靶密度等.光幕面内光能分布不均匀使得计时误差较大,直接影响测量精度.光幕光能分布均匀性的测量主要是为研究更大规模的光幕靶和密集度靶提供必要的数据准备和理论基础,有助于提高光幕测试的精度.从理论上介绍了激光光斑能量分布情况,对激光平行光幕的设计原理进行了说明,完成了激光平行光幕光能均匀性的测量实验,并使用origin软件对测量数据进行了分析.实验结果与理论分析相符,证明了测量方法的可行性.
Laser parallel light curtain can be extensively used to measure the diameter of the object,the velocity and coordinate of the projectile,the density of projectile in target etc.The uneven distribution of light energy made timing error,directly influencing the accuracy of measurement.The measurement of the uniformity of light energy distribution mainly provides data preparation and theoretical basis for the study of larger screen and dense target,and improves the precision of the curtain tests.The energy distribution of laser spot is introduced theoretically,the design principle of the laser parallel light curtain is explained,the experiment of measuring parallel light uniformity was completed,and the measurement data use of the origin software was analyzed.The experimental results are conformable to the theoretical analysis,the feasibility of the measurement method is proved.
