Two-dimensional optical fiber array

Abstract

The two-dimensional optical fiber array comprises hundreds of optical fiber units, a positioning grid plate and an optical fiber positioning frame. According to the two-dimensional optical fiber array, a ZrO2 micro ceramic tube is used as an optical fiber positioning matrix to manufacture an optical fiber unit; high hardness and precision machining size of the ZrO2 micro ceramic tube are utilized,the positioning grid plate and the optical fiber positioning frame made of softer metal (preferably copper or aluminum) are combined, and positioning of an optical fiber core is realized through mutual extrusion of the micro ceramic tubes and close contact or interference contact with the inner wall of the optical fiber positioning frame. Thus, the high-precision positioning problem of hundreds of optical fiber cores in the two-dimensional optical fiber array is solved, and the processing difficulty of the optical fiber positioning frame is reduced. The two-dimensional optical fiber array hasthe characteristics of accurate optical fiber core positioning and easiness in manufacturing.

Description

technical field [0001] The invention relates to the field of image information collection and transmission, in particular to a two-dimensional optical fiber array. Background technique [0002] With the continuous development of optical fiber communication, optical fiber arrays have been used more and more as a main way of image information acquisition and transmission. With the demand for higher quality and larger range of two-dimensional image acquisition and transmission, the traditional The two-dimensional optical fiber array formed by the simple arrangement of several or dozens of optical fibers can no longer meet the requirements of the two-dimensional image acquisition range and pixel positioning accuracy in some special physical tests. However, since the core of the optical fiber itself is a brittle glass fiber or soft plastic fiber, as the number of optical fibers increases, it will be more difficult to locate each optical fiber in the array. Under the requirements...

[0002] With the continuous development of optical fiber communication, optical fiber arrays have been used more and more as a main way of image information acquisition and transmission. With the demand for higher quality and larger range of two-dimensional image acquisition and transmission, the traditional The two-dimensional optical fiber array formed by the simple arrangement of several or dozens of optical fibers can no longer meet the requirements of the two-dimensional image acquisition range and pixel positioning accuracy in some special physical tests.

However, since the fiber core itself is a brittle glass fiber or soft plastic fiber, as the number of fibers increases, it will be more difficult to position each fiber in the array.
