为研究快中子照相空间分辨率和反差灵敏度对细节灵敏度技术指标的影响,实验采用控制变量对照方法,加工了相同深度不同孔径和相同孔径不同深度的聚乙烯和铅样品,得到了不同条件下快中子照相照片,经过图像处理,分析得出细节灵敏度受空间分辨率和反差灵敏度综合影响,当孔径较小时,空间分辨率起主要作用;当孔径较大时反差灵敏度起主要作用,最后给出了细节灵敏度的初步参考结论。
In order to study the influence of spatial resolution and contrast sensitivity of fast neutron photographic technique on the detail sensitivity specifications, a control variable control method was used to process polyethylene and lead samples of the same depth, different pore sizes and different depths of the same pore size. Fast neutron photogrammetry, after image processing, the analysis shows that the detail sensitivity is affected by the combination of spatial resolution and contrast sensitivity. When the aperture is small, the spatial resolution plays a major role. When the aperture is large, the contrast sensitivity plays a major role. Finally, Out of the details of the sensitivity of the initial reference conclusions.
