摘要：

采用反复蒸馏提纯技术和开放式动态蒸馏相结合的工艺, 制备了高纯As-S玻璃, 基本消除了玻璃在2.9、4和6.3 μm处的杂质吸收。利用旋转法制备出壁厚均匀、表面质量优异的硫系玻璃套管。采用棒管法拉制出丝径50 μm, 芯径40 μm具有芯包结构的硫系玻璃光纤。拉制的As-S光纤机械性能和光学性能优异, 光纤丝径波动小于1%, 弯曲半径优于4 mm, 中红外波段损耗基线小于0.5 dB/m。制备出像元呈正方形排列, 出端规格64×9, 入端规格192×3, 用于线-面转换的红外传像束, 像束断丝率为2.7%。利用该异型传像束成功实现了长线阵的红外推扫成像。

Abstract:

High-purity As-S glasses were prepared by repetitive distillation and open-type dynamic distillation methods. The intensities of impurities’ absorptions were obviously reduced at 2.9 μm, 4 μm and 6.3 μm. Chalcogenide glass tubes with precise wall thickness and fine surface properties were prepared by tube-rotating technique and the fibers with core of 40 μm, cladding of 50 μm and error of 1% in diameter were drawn by rod-in-tube method. The fiber had good mechanical and optical performances, which general optical loss was less than 0.5 dB/m and the bending radius was less than 4 mm based on the bending test. The line-plane-switching fiber bundle which format was 64×9 quadrate array to implement 192×3 linear array was made from these chalcogenide glass and long-array infrared push-broom image was successfully demonstrated. The results prove that the fibers and bundle have excellent properties and push-broom infrared system based on the line-plane-switching fiber bundle being feasibility.

Key words: chalcogenide glass fibers, coherent fiber bundle, impurities eliminating, infrared imaging
