The Design of Signal Collection and Adjustment Circuit of Infrared Sky Screen

HAN Feng,LIU Qunhua(School of Optoelectronic Engineering,Xi'an Technological University,Xi'an 710032,China)  
In the paper,photoelectric detection system and its signal processing circuit of the infrared sky screen were designed.This system can capture the signal as the projectile flies across the sky screen and the digital filter circuit were designed based on CPLD.So,the noise was removed.The experiment result indicates that the infrared sky screen has the advantages of large effective screen area,flexibility,high sensitivity and strong anti-interference ability.The system can be utilized to measure the velocity of the several projectiles and trig the other pertinent equipments.
