Design of Calibration System for Motion Attitude Measurement of Large-caliber Projectile

To meet the large-caliber projectile motion measurement system calibration requirement, developed a large-caliber projectile motion measurement system calibration system, gives the calibration principle and working process, design a visibility good green light source as the collimating light source, the design targets based on the filtering and PSD field grid position detection module; Aiming at the calibration requirement that the six faces of cavity cross grids frame cannot be shielded, the cavity cross grids adjustment module is designed. Error analysis shows that the calibration error of the system is 0.062mm.
