我们提出了一个灵活的相干中红外（中红外）光纤束的热成像制成的1200 Ge30As13Se32Te25玻璃芯嵌入在氟化乙烯丙烯（FEP）聚合物包层。硫族化物玻璃和聚合物包层之间的高折射率对比度有助于最小化像素间串扰，而聚合物包层的低杨氏模量赋予束良好的柔性，尽管其外径为毫米级。通过62.5cm长的束传递人手的高对比度和高空间分辨率热图像表明其优异的成像潜力。
We present a flexible coherent Mid-Infrared (Mid-IR) fiber bundle for thermal imaging made of 1200 Ge30As13Se32Te25 glass cores embedded in a Fluorinated Ethylene Propylene (FEP) polymer cladding. The high index contrast between the chalcogenide glass and the polymer cladding helps minimizing inter-pixel cross-talk, while the low Young's modulus of the polymer cladding gives the bundle good flexibility despite its millimeter scale outer diameter. The delivery of high contrast and high spatial resolution thermal images of a human hand through a 62.5 cm long bundle indicates its excellent imaging potential.
