Embodiment Construction

[0046] The concrete realization mode of the present invention is:

[0047] (1) The preform is made by PCVD process, and the monofilament is drawn. The preform is a two-layer coaxial structure, such as Figure 1a , Figure 1b As shown, the diameter of the core layer 11 is 17mm, and the diameter of the cladding layer 12, that is, the diameter of the preform is 20mm, then the core-to-clad diameter ratio is 0.85, and its refractive index profile is as follows Figure 2a As shown, its refractive index profile can also be used as Figure 2b The prefabricated rod shown; the preformed rod is drawn into monofilaments with the same diameter in the range of 1 to 2 mm on an ordinary optical fiber drawing tower;

[0048] (2), the monofilament obtained by drawing is cut into the same length, and each section of 900mm is several sections long. After cleaning and drying it, get 270 monofilaments and arrange them in a densely packed manner, such as image 3 shown;

[0049] (3), put the mon...

Abstract

The invention relates to a method for manufacturing a high-resolution optical fiber image transmission bundle, which comprises the following steps: drawing a preform rod into monofilaments with the diameter of 0.5-3mm; then cutting the monofilaments into a plurality of sections with the same length, cleaning, drying, arranging and molding a proper number of the monofilaments by the close packing way, further placing a thin-walled outer sleeve therein, filling gaps, and further drawing multifilaments with the diameter of 0.5-3mm; cutting the multifilaments into the sections with the same length, corroding the outer sleeve wrapped on the outside of the multifilaments in acid solution, cleaning, drying, and further arranging by the close packing way for becoming a multifilament bundle; placing the multifilament bundle into the thin-walled outer sleeve, and using proper pure silicon dioxide glass filaments for filling the gaps among the multifilaments and between the multifilament bundle and the outer sleeve; and further placing the multifilament bundle in an ordinary drawing tower for drawing the optical fiber image transmission bundle with the diameter of 0.2mm-2mm. The method can manufacture the optical fiber image transmission bundle with high resolution, high pixel and flexibility and is simultaneously characterized by high yield and low cost.

Description

technical field [0001] The invention relates to a method for manufacturing a high-resolution optical fiber image transmission bundle, belonging to the field of light and image transmission. Background technique [0002] The optical fiber image transmission bundle is generally made of thousands or tens of thousands of monofilaments (single optical fibers) with a certain length and a diameter of several microns made of glass materials. In order to directly transmit image information, it is required that the positions of each monofilament (that is, each pixel) in the image beam at both ends of the image beam be closely arranged in a one-to-one relationship, that is, the positions of the incident end and the output end The relative position of each pixel on the end face is exactly the same. In this way, each monofilament can be regarded as an imaging unit, that is, a pixel, and the image can be decomposed by a large number of pixels and transmitted to the exit end respectively....
