| Abstract: | A rectangular laser screen system(RLSS)was designed to determine the projectile impact location.The rectangle laser screen consists of many same optical modules.The laser beam passes through collimators,expanders and Fresnel lens shape into optical module and focuses on detectors.Whenever a projectile passes the optical screen module,the corresponding photodetectors sense the event due to partial or full obscuration of the incident energy.Based on the relationship between electro-optical signal ... |
