摘要

本文介绍了一种基于气固电离原理的多媒体成像探测器的信号色散实验结果，特别强调了单x射线曝光双能射线摄影。研究结果表明，多媒体探测器技术具有良好的信号特性，适合于大量的成像应用。另一方面，由于迁移率色散和空间电荷的影响，漂移距离对振幅和半峰全宽都有显著影响。随着气体压力的增加，信号得到改善。

Optimization of the signal dispersion parameters of a dual-energy multimedia imaging sensor

In this study, experimental results on the signal dispersion of a multimedia imaging detector, operating on gaseous solid state ionization principles, with specific emphasis on single x-ray exposure dual-energy radiography, are presented. The results of this study indicate that the multimedia detector technology exhibits excellent signal characteristics suitable for a large number of imaging applications. On the other hand, drift distance causes significant effect on both the amplitude and full-width at half maximum (FWHM) due to mobility dispersion and space-charge. An improved signal results with increasing gas pressure.
