摘　　要：耐辐照光纤面板可广泛应用于工业X射线探测和医疗非晶硅平板探测器等领域,目前正在开发的光纤面板在430~900 nm难以精准调控光吸收玻璃的透过率,除此之外还存在抗析晶性能差的问题。本文重点研究了玻璃着色组分对光吸收玻璃透过率与抗析晶性能的影响,研制出对紫外-可见-近红外波长吸收效果极佳、抗析晶性能良好的光吸收玻璃。结果表明,调整光吸收玻璃引入量后,制备的耐辐照光纤面板透过率均能达到74%以上;光吸收玻璃引入量为2.0%(质量分数)和2.4%的面板在空间频率为10 lp/mm时,调制传递函数(MTF)响应仍然很明显,可满足耐辐照光纤面板对透过率、MTF的要求。本工作解决了目前国内耐辐照光纤面板在医疗、工业探伤及空间探测领域中存在的分辨率不足、对比度低、成像质量差等难题,实现了高分辨率、高对比度、高质量耐辐照光纤面板的国产化替代。The irradiation-resistant fiber optic panels can be widely used in industrial X-ray detection and medical amorphous silicon flat panel detectors,etc.The fiber optic panels currently under development are difficult to accurately regulate the transmittance rate of the light-absorbing glass in the wavelength range of 430~900 nm,in addition to the poor resistance to precipitation performance.This paper focuses on the effects of glass coloring components on the transmittance and anti-decrystallization performance of light-absorbing glass and develops light-absorbing glass with excellent absorption effect at ultraviolet-visible-near-infrared wavelength and good anti-decrystallization performance.The results show that after adjusting the introduction amount of light-absorbing glass,the transmittance of irradiation-resistant fiber optic panels can reach more than 74%.When the spatial frequency is 10 lp/mm,the modulation transfer function(MTF)of panels with 2.0%(mass fraction)and 2.4%light-absorbing glass is still very obvious,and it can satisfy the requirements of irradiation-resistant optical fiber panels for the transmittance and MTF.This work solves the problems of insufficient resolution,low contrast,and poor imaging quality of irradiation-resistant fiber optic panels in the fields of medical treatment,industrial flaw detection,and space exploration,and realizes the localization of high-resolution,high-contrast,and high-quality irradiation-resistant fiber optic panels.
