Straight Ballistic Measurement Using Reflective Light Screen Target of Single Column Light Source
A novel method of measuring a projectiles straight flight trajectory is proposed. A five-light-screen target was made up of a one column laser source, one optical detector and four strip mirrors. Flight parameters including trajectory and component velocity in three dimensions can be obtained. A principle comparison experiment with a steel ball was done on a smooth plane table. The relative difference of velocity measurement is less than 0.2% and the difference of position measurement is less than 2mm. The results indicated the method proposed in this paper is feasible.
