摘要: 成像板是强激光物理实验中用于记录X射线及粒子信号的重要工具。采用狭缝法和栅条法对Fuji BAS-SR型成像板的空间分辨特性进行了实验研究，测定了该型成像板的调制传递函数，并对极限空间分辨进行了验证。结果显示该型成像板所能响应的空间截止频率约为17 lp/mm。借助蒙特卡罗程序，对成像板自身对X射线响应的空间弥散特性进行了模拟计算，发现成像板自身产生的空间弥散远小于经过扫描仪扫描之后的空间弥散，表明目前成像板空间分辨能力主要受限于其专用的扫描仪。

Abstract: The imaging plate is an important tool in high power laser-matter interactions. The slit method is employed to measure the modulation transfer function of Fuji BAS-SR IP. Meanwhile, periodic streaks are used to verify the result. The cut-off space frequency of SR IP up to 17 lp/mm is demonstrated. The spatial dispersion of IP is simulated by the MC code FLUKA when it exposed to the 17.5 keV X-ray. Compared to the spatial dispersion of image scanned by scanner, much less spatial dispersion is engendered by IP. The results are helpful for the quantitative measure of IP, and improving the spatial resolution of IP in the experiments.
