Optical Design and Analysis of Laser Screen for Projectile Velocity Measurement

提出了以微珠玻璃原向反射屏和光纤光锥构建大面积激光测速靶的新方案,对微珠玻璃原向反射屏的反射率和原向反射光斑的光强分布进行了测试分析,并以此作为光学系统设计的依据.实验结果表明:光学系统设计合理,完全可用于各种弹丸初速的实际测量.

A laser screen system for projectile velocity measurement, including Scotchlite retroreflector and fiber optical taper is put forward. The reflectivity of Scotchlite retroreflector and light intensity distribution in the reflected light spot are measured and analyzed, which can serve as the basis for optical design. The experiment result indicates that the optical design is reasonable and feasible to realize initial velocity measurements of various projectiles.
