Abstract

The invention discloses a flexible high-resolution infrared chalcogenide glass optical fiber image transmission bundle and a manufacturing method. The optical fiber image transmission bundle is formed by closely stacking optical fiber multifilaments, the optical fiber multifilaments are formed by drawing optical fiber monofilament bundles, the optical fiber monofilament bundles are formed by closely stacking optical fiber monofilaments, the optical fiber monofilaments sequentially comprise chalcogenide glass fiber cores, chalcogenide glass inner coating layers and thermoplastics polymer outer coating layers from inside to outside, and the relation among the refractive index n1 of the chalcogenide glass fiber cores, the refractive index n2 of the chalcogenide glass inner coating layers and the refractive index n3 of the thermoplastics polymer outer coating layers is n1>n2>n3. The manufacturing process is simple and easy to control, the wire breakage rate of the optical fiber bundles is low, and the large-section high-resolution flexible infrared optical fiber image transmission bundle can be manufactured easily.

Description

technical field [0001] The invention belongs to the technical field of infrared optical fiber image transmission bundles, in particular to a flexible high-resolution infrared chalcogenide glass optical fiber image transmission bundle and a preparation method. Background technique [0002] In recent years, infrared chalcogenide glass optical fiber has been widely used in laser transmission, thermal image transmission, chemical and Biosensing, infrared spectroscopy and other fields have attracted much attention. Chalcogenide glass refers to an amorphous material formed by the elements of Group VIA of the periodic table S, Se, Te, and a certain amount of other metal or non-metal elements. Among chalcogenide glass fibers, the typical transmission spectral ranges of sulfide, selenide and telluride fibers are 1-6 μm, 2-8 μm and 4-12 μm, respectively. Using a flexible high-resolution chalcogenide glass optical fiber image transmission bundle as a transmission waveguide, connected...
