Long-distance transmission scintillator arrays enable high-resolution X-ray imaging and signal transmission in challenging environments such as aerospace machinery, nuclear reactor cores, and complex biological regions. However, advanced scintillator arrays are still limited to thin films and blocks, which are unable to simultaneously support both imaging and long-distance transmission functions. We address this limitation by designing scintillator active fiber arrays composed of glass embedded with CsCuX (X=Cl, Br, and I) nanocrystals. The scintillator glass forms through controlled crystallization of CsCuX, and low-loss (~5 m) active fibers are engineered into an array of approximately 1,600 pixels with high resolution (48 lp mm; limit: 60.7 lp mm) via waveguide structuring. This detector penetrates complex structures and enables effective low-dose imaging. Our approach supports scalable, high-density fiber-optic X-ray arrays, providing a new platform for advanced imaging in both scientific and industrial applications.
长距离传输闪烁体阵列能够在具有挑战性的环境中实现高分辨率X射线成像和信号传输，如航空航天机械、核反应堆堆芯和复杂生物区域。然而，先进的闪烁体阵列仍局限于薄膜和块状，无法同时支持成像和长距离传输功能。我们通过设计由嵌入CsCuX（X = Cl、Br和I）纳米晶体的玻璃组成的闪烁体有源光纤阵列来解决这一限制。闪烁体玻璃通过CsCuX的控制结晶形成，低损耗（约5米）有源光纤通过波导结构设计成具有高分辨率（48线对/毫米；极限：60.7线对/毫米）的约1600像素阵列。该探测器能够穿透复杂结构并实现有效的低剂量成像。我们的方法支持可扩展的高密度光纤X射线阵列，为科学和工业应用中的先进成像提供了一个新平台。
