【摘要】 该文研制了采用CCD逐行扫描技术的X射线数字化仪,与Scandiflash射线源构成瞬态脉冲X射线诊断系统,并将之应用于弹道研究。该数字化仪采用光电成像器件,将光信号转换成电信号,通过A/D转换,图像复原等技术,可以同时捕捉到弹道过程中 4个时刻的弹道轨迹图像。更多还原

【Abstract】 A set of X-ray digital imaging instrument which uses charge coupled device (CCD) to scan is developed. The X-ray digital imaging system is constructed for the diagnosis of transient phenomenon in ballistics with the existing Scandiflash X-ray source. The system utilizes photoelectric imaging devices to transform the ray signal to electrical signal. Through analog-to-digital transform and image recover technique, the system can acquire four images of trajectory’s trace at four different times in whole trajectory.更多还原
