Effect of Light-Absorbing Glass on Performance of Irradiation-Resistant Optical Fiber Panels
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.
