Abstract
The present application discloses a method for fabricating a fiber optic image inverter with an ultra-short twister. The method includes: drawing a glass rod with a low refractive index and a high strain point temperature into a surrounding pipe fiber; drawing a glass rod with a high refractive index and a high transmittance into a filling glass fiber, and then drawing into a casing pipe absorption fiber; uniformly surrounding an outer side of a cladding glass pipe with the surrounding pipe fiber, and matching a core glass rod and the cladding glass pipe to be drawn into a mono fiber; and then performing fabrication of a multi fiber, fabrication of a multi-multi fiber, heat press fusion and twisting operation in sequence. The fiber optic image inverter with an ultra-short twister with a high resolution and a high contrast and clear imaging is obtained and applied in a low-light-level image intensifier.
