GATE/Geant4 simulation of radiation attenuation in barite aggregate concrete: A comparative study with Phy-X/PSD and NIST XCOM

Barite-reinforced concrete is a cost-effective, low-toxicity alternative to lead for gamma-ray shielding. This study used the GATE Monte Carlo toolkit, built on Geant4, to simulate narrow-beam gamma-ray transmission through three barite concrete ...

PSD based three-dimensional measuring method

, 2005
本发明公开一种基于PSD的三维测量方法。使用由线阵PSD配合柱面镜头构成相机装置观测空间目标点P,得到空间点P在PSD相机的投影点u的位置信号。该位置信号可以唯一定义一个空间测量平面;当多个PSD相机同时使用时,由单一空间点P所获得的多个投影点u可以定义同样多个测量面;这些面非平行,其交点就是该空间点P;在这些平面方程可以确定的条件下,则该空间点P的位置可以由所述平面定义的坐标系下计算出来;为实现上述三维定位,要先对所使用PSD相机进行标定,获得参考坐标系与PSD投影点u的位置关系,当相机标定完成之后 ...
