摘要
Abstract
An optoelectronic device is developed for projectile speed measurement. The incident beam is input onto the projectile surface and weak reflected beam is output to the photodiode(GT101) by fibers at each station respectively. Output signals from GT101 are employed to trigger the internal timer of STC12C5A60S2 microcontroller. Based on the distance and signal time difference between the neighbor stations, the projectile speed can be calculated. Then, LCD controlled by microcontroller can display the projectile speed and communicate data between lower computer and host PC by serial ports. Finally, the projectile speed and current time histories of each diode can be saved in PC. The results show that this device is with good flexibility and reliability in measurement wide speed range of projectile from two-stage gas gun.关键词
